choose the corect answer and give brief explaination, this simple question thats why i make it as one question PT. ABCD has factories in 2 locations, namely in New York and New Jersey. To test whether there is a difference in the daily productivity of the two factories, a sample of 20 days of production was taken from each factory. Then the hypothesis being tested is ... Ho: u1 = u2 vs Ha: u1 > u2 All of the above is true Ho: u1 = u2 vs Ha: u1 not the same as u2 Ho: u1 = u2 vs Ha: u1 < u2 Of a random sample of 64 businessmen, 48 were classified as "successful". If it is known that the population proportion is 0.70, then the standard error of the proportion estimator is 0.0772 0.8728 0.0572 0.0033
In the initial test of the Salk vaccine for polio, 400,000 children were selected and divided into two groups of 200,000. One group was vaccinated with the Salk vaccine while the second group was vaccinated with a placebo. Of those vaccinated with the Salk vaccine, 33 later developed polio. Of those receiving the placebo, 115 later developed polio. Test the claim that the Salk vaccine is effective in lowering the polio rate. Use α= 0.01.
To inspect the quality of the screens for mobile phones produced by Company X, two separate inspection devices are used to test the screens for defects. Basically, a specific screen is tested once using the two inspection devices. Device 1 can detect the presence of defects 99.3% of the time, whereas Device 2 can detect defects 99.7% of the time. Assume that the 2 devices are operating independently from each other. One day, four defective screens were sent for inspection. Let X represent the number of screens that will be correctly tagged as defective by Device 1, while Y represents the number of screens that will be correctly tagged as defective by Device 2. Are X and Y independent? explain
For a one-tailed hypothesis test the critical value is 2.485. What is your statistical decision if t sTAT =+2.869 ? What is the statistical decision? A. Since the t STAT value is less than the critical value, reject H_{0} B. Since the t STAT value is greater than the critical value, do not reject . Since the t STAT value is greater than the critical value, reject H_{0} D. Since the t STAT value is less than the critical value, do not reject H_{0}
Twenty volunteers at a cold research institute caught a cold after having been exposed to various cold viruses. Ten of the volunteers were randomly selected to receive tablets containing 1 gram of vitamin C. These tablets were taken four times a day. The control group, consisting of the other 10 volunteers, was given placebo tablets that looked and tasted exactly like the vitamin C ones. This was continued for each volunteer until a doctor, who did not know whether one volunteer was receiving vitamin C or the placebo, decided that the volunteer was no longer suffering from the cold. The length of time the cold lasted was then recorded. At the end of the experiment, the following data resulted: The average length of cold for the n1 = 10 people treated with vitamin C is with a standard deviation of s1 = 0.76 The average length of cold for the n2 = 10 people receiving the placebo is with a standard deviation of s2 = 0.85 Determine the value of the pooled standard deviation .

The average drying time of a manufacturer’s paint is 20 minutes. Investigating the effectiveness of a modifica-tion in the chemical composition of her paint, the manu-facturer wants to test the null hypothesis μ = 20 minutes against a suitable alternative, where μ is the average dry-ing time of the modified paint. (a) What alternative hypothesis should the manufactureruse if she does not want to make the modification in thechemical composition of the paint unless it decreases thedrying time?(b) What alternative hypothesis should the manufactureruse if the new process is actually cheaper and she wants tomake the modification unless it increases the drying timeof the paint?
A pharmaceutical company has developed a new drug aimed at reducing the number of people affected by a particular disease. The current existing drug available on the market has a cure rate of 60%. However, before the pharmaceutical company can put the new drug on the market, the authorities need to be convinced that it is safe and more effective than the existing one. A trial is then set up. The new drug is given to 280 randomly selected patients who suffer from this disease. After the treatment, 196 people are cured. a) Is the new medicine more effective than the traditional one? Comment on your results. As a control group, 140 new patients who suffer from the same disease are selected at random but the patients in that group are given only (without knowing) vitamin C. After this “treatment” 70 people are cured. b) Is the vitamin worse than the traditional medicine in curing the disease? Comment on your results. c) On the basis of the evidence in part a) and part b) should the…
A breathalyser test is used by police in an area to determine whether a driver has an excess of alcohol in their blood. The device is not totally reliable: 6 % of drivers who have not consumed an excess of alcohol give a reading from the breathalyser as being above the legal limit, while 10 % of drivers who are above the legal limit will give a reading below that level. Suppose that in fact 12 % of drivers are above the legal alcohol limit, and the police stop a driver at random. Give answers to the following to four decimal places. Part a) What is the probability that the driver is incorrectly classified as being over the limit? Part b) What is the probability that the driver is correctly classified as being over the limit? Part c) Find the probability that the driver gives a breathalyser test reading that is over the limit. Part d) Find the probability that the driver is under the legal limit, given the breathalyser reading is also below the limit.
Due to a manufactoring error, three cans of regular soda were accidently filled with diet soda, placed into a 12-pack. Suppose that two cans were randomly selected from the 12-pack. A) determine the probabilty that that neither contain diet soda. Would this be unusual? B) Determine the probabilty that exactly one is diet.
An explosion at a construction site could haveoccurred as the result of static electricity, malfunctioningof equipment, carelessness, or sabotage. Interviews withconstruction engineers analyzing the risks involved ledto the estimates that such an explosion would occur withprobability 0.25 as a result of static electricity, 0.20 as aresult of malfunctioning of equipment, 0.40 as a result ofcarelessness, and 0.75 as a result of sabotage. It is alsofelt that the prior probabilities of the four causes of theexplosion are 0.20, 0.40, 0.25, and 0.15. Based on all thisinformation, what is(a) the most likely cause of the explosion;(b) the least likely cause of the explosion?
