Knowing that you’ve previously taken a statistics course, your boss asks you to “figure itout”. You create a survey to gauge employee interest in this area.1. Formerly, your place of employment has tried to give surveys to everyone, a census, but only a fewpeople responded to the email. Your new plan is to randomly choose some employees and administerthe survey yourself. You put everyone’s name on a numbered list and randomly choose numbers untilyou have your sample. What form of sampling is being described here?2. Suppose you want to estimate the percentage of employees who want to work from home.

The workers were being forced to work for more than 8 hours. 8 hours is the average/normal work time per day in the Philippines as stated in the Labor Code and was initially stipulated by their employer when they were hired. They also reported that they were not receiving any compensation for their overtime work. The lawyer commissioned you to conduct a survey involving 10 randomly selected workers from the factory to inquire about their work time. The data you collected is displayed below. 8 hours 6 hours 5 hours 10 hours 14 hours 3 hours 9 hours 8 hours 11 hours 14 hours Use the P-Value Approach in testing the complaint of the workers. 1) Estimate μ at 99% confidence interval. 2) If you drew the wrong conclusion and gave the labor lawyer the wrong advice, what type of error would you have committed?A study was recently conducted to assess the relationship between miscarriage and heavy alcohol use during the first trimester of pregnancy.

For the purpose of this study, heavy alcohol use was defined as consuming four or more drinks on any one occasion during the first trimester of pregnancy. Study results found that a total of 18 women were heavy alcohol users, 14 among those who suffered a miscarriage. 1) What type of study design was used? Explain. 2) Set up the 2X2 contingency table for the data. 3) For this type of study design, what is the appropriate measure to describe the strength of the association between exposure and disease? 4) Calculate the measure identified in question 3. 5) Interpret the measure calculated in question 4.

A random sample of subjects is selected from the population of names on a waiting list at a mental health clinic. For each subject selected, another subject is so, also from the waiting list, who resembles the original deselect exception in a number of important respects, such as age, length of time on the waiting list, IQ, severity of symptoms, length of symptoms duration, category of neurosis, and previous treatment history. By a flip of a coin, one group is chosen to receive six months of intensive Psychotherapy, while the other group is told to continued waiting and not to seek treatment elsewhere. At the end of the six-month period, a panel of expert judges all the subjects with respect to the extent of symptomatology. What type of research is this, experimental or post facto? What is the IV and what is the DV? What would you advise the researcher to do with…2.

The sample, "was basically a simple random sample of the population of the metropolitan area" of Detroit, Michigan. Of the 662 respondents, 276 were white Protestants and 224 were white Catholics. The study took place at the height of the cold war. One question asked if the right of free speech included the right to make speeches in favor of communism. Of the 276 white Protestants, 118 said "Yes" while 88 of the 224 white Catholics said "Yes." Give a 80% confidence interval for the difference between the proportion of Protestants who agreed that communist speeches are protected and the proportion of Catholics who held this opinion. Follow the Inference Toolbox. lower bound: upper bound:4. A pharmaceutical company wants to test whether the incidence of side effects (i.e. adverse events)differs between the treatment and placebo groups at theα= 0.05. Letp1= the proportion of subjects in the treatment groups who experienced at least one adverse event and letp2= the proportion of subjects in the placebo group who experience at least one adverse event. 8 out of 30 people in the treatment group experienced at least one adverse event and 5 out of 30 people in the placebo group experienced at least one adverse event.

- A researcher wants to know if people from different social classes (lower, working, middle, upper classes) vary in their support for same-sex marriage. The researcher measured the attitudes of people from different social classes toward same-sex marriage by asking if they think homosexuals should have right to marry (1=strongly disagree, 2=disagree, 3=agree, 4=strongly agree). The researcher hypothesized that social classes will vary significantly in their support for same-sex marriage. To test the hypothesis, the researcher conducted a one-way ANOVA and obtained the following results. ANOVA HOMOSEXUALS SHOULD HAVE RIGHT TO MARRY Sum of Squares df Mean Square F Sig.

Peripheral catheters retained in a blood vessel are a common cause of peripheral vascular catheter-related bloodstream infections (PVC-BSIs) (Sato et al. 2017). Patients with PVC-BSIs appear to also have other infections such as Staphylococcus aureus (S. aureus). Researchers want to know if having an S. aureus infection is associated with dying from a PVC-BSI. In a recent trial, 187 patients were studied. 76 patients that had an S. aureus infection also died of a PVC-BSI. 35 patients died of a PVC-BSI but did not have an S. aureus infection. 22 patients had an S. Aureus infection but did not die of a PVC-BSI. Finally, 54 patients did not have an S. aureus infection and did not die of a PVC-BSI. Test the claim that PVC-BSI mortality is dependent upon having an S. aureus infection. Use a 0.05 significance level. a. 0.31 b. 0.45 c. 3.94 d. 2.14 e. 4.54
