5 An experiment is designed to test whether a new drug can be used to reduce auditory hallucinations inschizophrenics. Schizophrenics who experience auditory hallucinations are randomly assigned toreceive either a placebo drug, a very low dosage, a moderate dosage, or a high dosage of the drug. Theresults of the experiment show that the moderate dosage is the most effective. What is the majorproblem with this experiment?O There is a possible order effectO There is no control group that receives no drug at allThe participants weren't matched for occurence of auditory hallucinationsO The study isn't a true experiment

Introduction: There are 4 possible treatments- the placebo, a very low dosage of the drug, a…

A researcher is interested in estimating the extent to which posting caloric labels on menus changes the number of calories consumed by patrons. To test the impact of posting caloric labels on menu items, the analyst created two menus for the same restaurant: One menu with caloric labels and one menu without. As soon as restaurant guests entered the restaurant, they were randomly assigned one of the two types of menus. For the sake of clarity, guests assigned the menu with caloric labels are referred to as “Group 1” or the “treatment group”. Likewise, guests assigned the menu without caloric labels are referred to as “Group 2” or the control group. The analyst then collected data detailing how many calories each guest consumed as well as recording the age of each guest. The variable Cal1 denotes the number of calories consumed by guests who were assigned to the treatment group 1, while the variable Cal2 denotes the number of calories consumed by guests who were assigned to the control…
A researcher hypothesized that people are more likely to be aggressive when they are criticized than when they are not. The researcher randomly assigned participants to one of two groups: 1) in group 1 participant's essay was given a negative rating, and 2) in group 2 participant's essay was given a positive rating. Then the researcher monitored how many loud blasts participants delivered in a confederate's earphones in the next room. One person dropped out of the study, so that there were 8 people in treatment condition 1 (n1 = 8) and 7 people in treatment condition 2 (n2 = 7). The alpha was .05. The mean number of blasts for Group 1 was 6.8 (SS = 80) and the mean number of blasts for Group 2 was 3.5 (SS = 78). What is the alternative hypothesis for this study? Is this a directional or non-directional hypothesis? The critical t is ___________. The calculated t is _______.
A university researcher knowledgeable in Chinese medicine conducted a study to determine whether acupuncture can help reduce cocaine addiction. In this experiment, 18 cocaine addicts were randomly assigned to one of three groups of 6 addicts per group. One group received 10 weeks of acupuncture treatment in which the acupuncture needles were inserted into points on the outer ear where stimulation is believed to be effective. Another group, a placebo group, had acupuncture needles inserted into points on the ear believed not to be effective. The third group received no acupuncture treatment; instead, addicts in this group received relaxation therapy. All groups also received counseling over the 10-week treatment period. The dependent variable was craving for cocaine as measured by the number of cocaine urges experienced by each addict in the last week of treatment. The following are the results. Acupuncture + Counseling Placebo + Counseling Relaxation Therapy + Counseling…
A neurosurgeon believes that lesions in a particular area of the brain, called the thalamus, will decrease pain perception. If so, this could be important in the treatment of terminal illness that is accompanied by intense pain. As a first attempt to test this hypothesis, he conducts an experiment in which 16 rats are randomly divided into two groups of eight each. Animals in the experimental group receive a small lesion in the part of the thalamus thought to be involved with pain perception. Animals in the control group receive a comparable lesion in a brain area believed to be unrelated to pain. Two weeks after surgery, each animal is given a brief electrical shock to the paws. The shock is administered in an ascending series, beginning with a very low intensity level and increasing until the animal first flinches. In this manner, the pain threshold to electric shock is determined for each rat. The following data are obtained. Each score represents the current level (milli-amperes)…
A hearing specialist conducts a study on hearing loss at certain frequencies among a group of patients in a retirement community. Of 94 residents tested, 10 had significant hearing loss at low frequencies but not high, 40 had a significant loss at high frequencies but not low, and 26 showed no significant hearing loss at all. How many residents had hearing loss at both low and high frequencies?
A double-blind, randomized comparative experiment compared the effect of the drug lorcaserin and a placebo on weight loss in overweight adults. All subjects also underwent diet and exercise counseling. The study reported that, after one year, patients in the lorcaserin group had an average weight loss of 5.8 kilograms (kg), while those on the placebo had an average weight loss of 2.2 kg (P < 0.001). Explain to someone who knows no statistics why these results mean that there is good reason to think that lorcaserin works. Include an explanation of what P < 0.001 means.
The makers of a smartphone have received complaints that the face recognition tool often doesn't work, or takes multiple attempts to finally unlock the phone. They've upgraded to a new version and are claiming the tool has improved. To test the claim, a critic takes a random sample of 80 users of the new version (Group 1) and 75 users of the old version (Group 2). He finds that the face recognition tool works on the first try 70% of the time in the new version and 56% of the time in the old version. Can it be concluded that the new version is performing better? Test at α=0.10. Hypotheses: H0: p1 = p2 H1: p1 > p2 In this scenario, what is the p-value? Round to four decimal places. p-value=
It is believed that sunlight offers some protection against multiple sclerosis (MS), but the reason is unknown. Researchers randomly assigned mice to one of: Control (nothing), Vitamin D Supplements, and UV Light. All mice were injected with proteins known to induce a form of MS, and they observed which mice got MS. In testing whether Vitamin D provides protection against MS (Vitamin D vs control group), the p-value is 0.47. Write down A) null and alternative hypothesis
A 1980 study investigated the relationship between the use of OCs and the development of endometrial cancer. The researchers found that of 117 endometrial-cancer patients, 6 had used the OC Oracon at some time in their lives, whereas 8 of the 395 controls had used this agent. Test for an association between the use of Oracon and the incidence of endometrial cancer, using a two-tailed test.
Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent study, 82 patients with Type 2 diabetes underwent this procedure, and 59 of them experienced a recovery from diabetes. Does this study provide convincing evidence that less than 75% of those with diabetes who undergo this surgery will recover from diabetes? Use the =α0.10 level of significance and the P-value method with the TI-84 Plus calculator. STATE THE NULL AND ALT HYP
A pharmaceutical company wants to test whether Aspirin 1 is as effective as Aspirin 2. A random sample of 400 people with headaches are given Aspirin 1 and 260 report they feel better within 1 hour. Another independent random sample of 350 people with headaches are given Aspirin 2 and 220 report they feel better within 1 hour.a) At the 1% level of significance, does there appear to be a difference in theeffectiveness of the 2 types of Aspirin?b) What is the p-value?
A psychologist is interested in people’s assessment of life happiness and how it relates to positive lifestyle changes. The researcher randomly assigns 42 individuals to one of two groups: Exercise Only, and Exercise and Healthy Eating. The researcher believes that Group 1 (n = 21; Exercise and Healthy Eating) will be significantly happier than Group 2 (n = 21; Exercise Only). Perform the correct test of significance, with alpha = .05. Be sure to write out your hypotheses and final decision.
