In a study of proctored and nonproctored tests in an online Intermediate Algebra course, researchersobtained the data for test results given below.Group 1 (Proctored): n = 35,30.74=x, s = 12.87Group 2 (Nonproctored): n = 32.62.88=x, s = 22.09 Use a 0.01 significance level to test the claim that students taking non-proctored test get a higher meanthan those taking proctored tests.
Medical tests were conducted to learn about drug-resistant tuberculosis. Of 142 cases tested in New Jersey, 9 were found to be drug-resistant. Of 268 cases tested in Texas, 5 were found to be drug-resistant. Do these data suggest a statistically significant difference between the proportions of drug-resistant cases in the two states? Use a .02 level of significance. What is the -value, and what is your conclusion? Test statistic =
Textbook authors must be careful that the reading level of their book is appropriate for the target audience. Some methods of assessing reading level require estimating the average word length. We've randomly chosen 20 words from a randomly selected page in Intro Stats and counted the number of letters in each word: 5, 5, 2, 11, 3, 5, 6, 8, 5, 4, 7, 2, 9, 4, 8, 10, 4, 7, 6, 9 Suppose that our editor was hoping that the book would have a mean word length of 6.8 letters. Does this sample indicate that the authors failed to meet this goal? With a significance level of 0.05, test an appropriate hypothesis and state your conclusion. (i.e state the appropriate null and alternative hypotheses, calculate the test statistic, conclude and interpret it).

In June 2015, Gallup conducted a poll of a random sample of 14802 adults to determine the well-being of people living in the United States. One question asked, "Did you exercise at least 30 minutes for 3 or more days in the past week?" In the survey, 57.3% of males and 42.7% of females responded yes to this question. Which of the following is true about this scenario?A. 57:3% and 42.7% are both statistiesB. 57.3% and 42.7% are both parameter.C. If we took another random sample of 14802 adults, we would expect to get the exact same results.
18. Car and Taxi Ages When the author visited Dublin, Ireland (home of Guinness Breweryemployee William Gosset, who first developed the t distribution), he recorded the ages of randomlyselected passenger cars and randomly selected taxis. The ages can be found from thelicense plates. (There is no end to the fun of traveling with the author.) The ages (in years) arelisted below. We might expect that taxis would be newer, so test the claim that the mean age ofcars is greater than the mean age of taxis.

A government study found that people who eat chocolate frequently weighless than people who don’t. Researchers questioned 1000 individuals fromCalifornia between the ages of 20 and 85 about their eating habits, andmeasured their weight and height. On average, participants ate chocolatetwice a week and had a body mass index (BMI) of 28. There was anobserved difference of five to seven pounds in weight between those whoate chocolate five times a week and those who did not eat any chocolate atall, with the chocolate eaters weighing less on average. Frequent chocolateeaters also consumed more calories, on average, than people who consumedless chocolate. Based on this summary, would you recommend thatAmerican’s who do not presently eat chocolate, consider eating chocolateup to five times a week if they want to lose weight? Why or why not?Explain.
A report on the U.S. economy indicates that 30% of Americans have experienced difficulty in making mortgage payments. A news organization randomly sampled 400 Americans from 10 cities named the “fastest dying cities in the U.S.” (Forbes Magazine, August 2008) and found that 140 reported such difficulty. Does this indicate that the problem is more severe among these cities? a. Write the null and alternative hypotheses. b. What is the value of the test statistic? c. What is the associated P-value? d. State your conclusion using α = 0.05.
