A drugs company produced a new pain-relieving drug for migraine sufferers and its advertisements stated that the drug had a 90% success rate. A doctor doubted whether the drug would be as successful as the company claimed. She prescribed the drug for 15 of her patients. After six months, 11 of these patients said that their migraine symptoms had been relieved by the drug. 1. Test the drug company’s claim, at the 5% level of significance 2. Should the doctor continue to prescribe the drug?

The athletic director at a large university compared the proportions of freshmen (1st year students) and seniors (4th year students) who exercise regularly. She analyzed the data and found the Z-statistic for the difference between the population proportions to be 2.43 with a P-value of 0.015. The level of significance was set at 0.05. State the conclusion she can draw about the difference between the two population proportions.
A psychologist is interested investigating the proportion of depressed teenagers in a particular city. Using a sample of 40 teenagers, 16 were found to exhibit symptoms of depression. At ?=0.01,test the claim that more that 35% of teenagers who live in the city exhibit symptoms of depression.
Lucy recently asked the servers at her restaurant to only give straws to customers who request them. She thinks that about half of the customers will ask for straws but hopes that the rate will be less than half. She randomly selects 100 customers and finds that 43 of them ask for a straw. To determine if these data provide convincing evidence that the proportion of customers who will ask for a straw is less than 50%, 150 trials of a simulation are conducted. Lucy is testing the hypotheses: H0: p = 50% and Ha: p < 50%, where p = the true proportion of customers who will ask for a straw. Based on the results of the simulation, the estimated P-value is 0.0733. Using a = 0.10, what conclusion should Lucy reach? Because the P-value of 0.0733 < a, Lucy should reject H0. There is convincing evidence that the proportion of customers who will ask for a straw is less than 50%. Because the P-value of 0.0733 < a, Lucy should reject Ha. There is not convincing evidence that the…
The “promotions manager” of a large cosmetics manufacturer wanted to investigate user acceptance with a new formulation of their popular female facial cream. She organised for a sample of 5,000 users of the new formulation to be selected and sought their feedback on whether they were satisfied with its effects or not. Of the 2800 responses gained, 2,100 indicated that they were satisfied with the new formulation. i. State the name and the value of the statistic that is the best estimate for the proportion of all potential cream users that are satisfied
A study was performed to determine the percentage of people who wear life vests while out on the water. A researcher believed that the percentage was different for those who rode jet skis compared to those who were in boats. Out of 500500 randomly selected people who rode a jet ski, 85%85% wore life vests. Out of 250250 randomly selected boaters, 90.4%90.4% wore life vests. Using a 0.050.05 level of significance, test the claim that the proportion of people who wear life vests while riding a jet ski is not the same as the proportion of people who wear life vests while riding in a boat. Let jet skiers be Population 1 and let boaters be Population 2. Step 1 of 3 : State the null and alternative hypotheses for the test. Fill in the blank below.

In order to track the percentages of misdiagnoses by emergency room doctors, a sample of 950 patients revealed that 45 patients were misdiagnosed with indigestion instead of a heart attack. Historically, it was believed that physicians misdiagnose 7% of heart attacks. Using an a=0.05 level of significance, Complete the following steps to determine if this study proves that the misdiagnosis rate is less than the historical 7%? (NOTE: All areas are reported to four decimal places; all z-scores are reported to two decimal places except the two special cases listed at the bottom of the table.) Insert the following values from the question: p= % = (two decimals) (two decimals) n3= (four decimals) Set up the hypothesis statements (no spaces between characters): Ho H Based on the hypothesis statements, will you use a or (1- a) to solve for zent? What area will you use on the z-score table to find zert? What is the value of z?
Two separate samples receive two different treatments. The first treatment group (N = 9) has a mean of 50 with SS = 710. The second treatment group (N = 6) has a mean of 60 with SS = 460. Is the second treatment group significantly larger than the first? What is the effect size?

As the manager of a fashion brand, you have recently run a large-scale campaign to draw attention to your company's CSR activities and thus improve the brand's image. In order to evaluate the efficiency of the campaign, you conducted a survey at major fashion stores to measure the attitudes towards. your brand at two points of time: before the campaign started and after the campaign finished. By summing up respondents' answers to 3 questions (each measuring a particular aspect of attitude on a 1-5 scale), a single overall measure of attitude is obtained for each participant. This measure can therefore range from 3 to 15, with a score of 3 representing and extremely negative attitude and a score of 15 representing an extremely positive attitude. To check whether male and female customers have different attitudes towards you company, as well as to test whether the campaign may have affected males and females differently, you ask the respondents to report their gender. You analyse the…

The wrong alternative. One of your friends is testing the effect of drinking coffee on the duration of cold symptoms. The common cold lasts, on average, 6 days. Your friend starts with no expectations as to whether drinking coffee will have any effect on cold duration. After seeing the results of the experiment, in which the average cold duration was less than 6 days, your friend tests a one-sided alternative about the population mean cold duration when drinking coffee, H0: lcoffee = 6 На: Which gives a one-sided P value P = 0.0465. Explain why your friend should have used a two-sided hypothesis. Hcoffee < 6
