1. A pharmaceutical company is testing their new nicotine patch. They randomly assign 100 volunteers to the patch and finding that 37 had quit smoking after 8 weeks. Compute the 96% confidence interval to estimate proportion people who quit smoking after 8 weeks with the new nicotine patch. Interpret this confidence interval. do not check CLT here.

b) The pharmaceutical company repeats their test, this time randomly assigning volunteers to use the patch and finding that 49 had quit smoking after 8 weeks. Compute the 98% confidence interval to estimate the proportion of people who quit smoking after 8 weeks with the new nicotine patch. Does this support the company's claim that over half of people on the patch quit smoking after 8 weeks? You do NOT need to check CLT here.

1.Quit Smoking: The New England Journal of Medicine published the results of a double-blind, placebo-controlled experiment to study the effect of nicotine patches and the antidepressant bupropion on quitting smoking. The target for quitting smoking was the 8th day of the experiment. In this experiment researchers randomly assigned smokers to treatments. We conducted a hypothesis test to determine if the side effect rates are significantly different for nicotine patches versus bupropion at a 5% level of significance. (The normality conditions...

A pharmaceutical company is testing a new drug to increase memorization ability. It takes a sample of individuals and splits them randomly into two groups. After the drug regimen is completed, all members of the study are given a test for memorization ability with higher scores representing a better ability to memorize. Those 21 participants on the drug had an average test score of 29.077 (SD = 4.199) while those 30 participants not on the drug had an average score...

A pharmaceutical company is testing a new drug to increase memorization ability. It takes a sample of individuals and splits them randomly into two groups. One group is administered the drug, and the other is given a placebo. After the drug regimen is completed, all members of the study are given a test for memorization ability with higher scores representing a better ability to memorize. You are presented a 90% confidence interval for the difference in population mean scores (with...

A new drug to treat high cholesterol is being tested by pharmaceutical company. The cholesterol levels for 18 patients were recorded before administering the drug and after. The average difference in cholesterol levels (after - before) was 4.19 mg/dL with a standard deviation of 8.055 mg/dL. Using this information, the calculated 90% confidence paired-t interval is (0.887, 7.493). Which of the following is the best interpretation of this interval? Question 8 options: 1) The proportion of all patients that had...
