Body Mass Index is a measure of body shape. Duran et al. (2013) investigated BMI in Texas youth. In part of the study, they took BMI measurements on samples of 14 year old boys and girls in Texas (94 boys and 98 girls). Suppose they were interested in investigating a possible difference in body mass index between boys and girls at that age. Assume for the purposes of this question that the samples can be thought of as independent simple random samples from 14 year old Texans, and that all other assumptions of the Welch t procedure are met.

A union of restaurant and foodservice workers would like to estimate this year's mean hourly wage u for foodservice workers in the U.S. Last year's mean hourly wage was $8.08, and there is good reason to believe that this year's value is less than last year's. The union decides to do a statistical test to see if it can be concluded that the mean has decreased. The union chooses a random sample of 75 wages from this year. Suppose that the population of hourly wages of foodservice workers in the U.S. has a standard deviation of $1.25 and that the union performs its hypothesis test using the 0.10 level of significance. Based on this information, answer the questions below. Carry your intermediate computations to four or more decimal places, and round your responses as indicated. (If necessary, consult a list of formulas.) (a) What are the null hypothesis Ho and the alternative hypothesis H, that the union should use for the test? Ho: D H₁: 0 (b) Assuming that the actual value of μ is…

Fast ‘n Clean operates 12 laundromats on the east side of the city. All of Fast ‘n Clean’s clothes dryers have a label stating “20 minutes for $1.00.” You question the accuracy of the dryers’ clocks and decide to conduct an observational study. You randomly select 36 dryers in several different Fast ‘n Clean locations, put $1.00 in each and time the drying cycle. The sample mean drying time is 20 minutes and 25 seconds. The manufacturer of the dryer states that the standard deviation for 20-minute drying cycles is 1 minute. a. Using the sample data and α = .05, test the validity of the label on the dryers. Apply the p-value and critical value approaches to conducting the two-tail hypothesis test b. Conduct the same two-tail hypothesis test, but use the confidence interval approach to hypothesis testing.
An article claimed that "those with a college degree reported a higher incidence of sunburn than those without a high school degree—45 percent versus 26 percent." For purposes of this exercise, suppose that these percentages were based on random samples of size 200 from each of the two groups of interest (college graduates and those without a high school degree). Is there convincing evidence that the proportion who experience a sunburn is higher for college graduates than it is for those without a high school degree? (Use pcollege graduates − pwithout a high school degree. Round your test statistic to two decimal places and your P-value to four decimal places.) z = P =
A company manufactures printers and fax machines at plants located in Atlanta, Dallas, and Seattle. To measure how much employees at these plants know about quality management, a random sample of 6 employees was selected from each plant and the employees selected were given a quality awareness examination. The examination scores for these 18 employees are shown in the following table. The sample means, sample variances, and sample standard deviations for each group are also provided. Managers want to use these data to test the hypothesis that the mean examination score is the same for all three plants.

In order to evaluate the effects of stress on the development of stomach ulcers, three separate groups of monkeys were trained to avoid shock by performing a simple avoidance task, a complex avoidance task or a very complex avoidance task. The more complex the task, the less successful the monkeys were at avoiding electric shock. After several weeks of this, the number of stomach ulcers the monkeys had in each group were counted. Which statistical test should be used to compare ulcers across the three groups? Select one: a. One-way between subjects ANOVA b. One-way repeated measures ANOVA c. Two-way between subjects ANOVA d. None of these options
Are these results statistically significant or not?
Parking at a large university has become a very big problem. University administrators are interested in determining the average parking time (e.g. the time it takes a student to find a parking spot) of its students. An administrator inconspicuously followed 250 students and carefully recorded their parking times. The university is interested in using the information from the sample of 250 students collected to learn information about the entire student parking population. Would this be an application of descriptive or inferential statistics?
2) What percentage of Contra Costa County adults supports a ban on assault-style weapons? Suppose that we survey a random sample of 100 adults living in Contra Costa County and find that 62% support a ban on assault-style weapons. According to a 2015 study by the Pew Research Center, 57% of U.S. adults favor a ban on assault-style weapons. Assuming that the variability in random samples will be the same in Contra Costa County as in the U.S., find the 95% confidence interval to estimate the proportion of CCC adults that favor a ban on assault-style weapons. a) Verify that the conditions for the use of the normal model are met using the 2015 study. b) Why do we check conditions for use of the normal model? c) Calculate the standard error based on the 2015 study. What does this humber tell us? d) Find the 95% confidence interval for Contra Costa County. e) Write a sentence to interpret the interval. f) Are we confident that the majority of Contra Costa County residents support a ban on…
You want to run an ANOVA looking at the effect of attending review sessions on students’ statistics grades.
