"Tiger Woods uses Titleist brand golf clubs" the salesperson says to me. He promises me that my game will improve if I buy the expensive Titleist clubs which are, after all, endorsed by Tiger. But I am a smart consumer, and rather than wasting money on expensive clubs, I first want to know if they work. So, I borrow the Titleist clubs and have 5 randomly selected golfers use them, recording their scores. I also have 6 other randomly selected golfers use my old clubs. Using the data below and the steps of hypothesis testing, test the salesperson's claim that the Titleist clubs will produce a lower score than my clubs (lower is better). Set a = .05.

There is a notion that early discrimination training increases the IQ of children; that is, color discriminations (particularly subtle ones), discriminations among musical tones, etc., if fostered in children, are expected to increase IQ. A group of identical twins is used in an experiment to test this theory. One member of each twin pair gets this early discrimination training, but the other does not. Then, at a later date, their respective IQ scores are obtained. Which statistic would be used to test the hypothesis? a. One Factor ANOVA b. t-test for r > 0 c. r-squared or r d. Z-test e. Chi-square test f. One Sample t-test g. Two factor ANOVA h. Point Biserial r i. Cramer’s Phi j. Phi Coefficient k. Dependent groups t-test L. Independent groups t-test m. Eta-squared

A study was done to determine whether the proportion of women who had accidents on Friday the 13th was greater than the proportion of men who had accidents on Friday the 13th. To find out, a random sample was taken of 2,000 individuals. Each individual was asked their gender and whether they had been involved in an accident on Friday the 13th. a)What is the explanatory variable, and is it quantitative or categorical? b)What is the response variable, and is it quantitative or categorical? c)What procedure should be used for this test?
The accompanying table gives data from a survey of new car owners conducted by J.D. Power and Associates (USA TODAY, usatoday.com, March 29, 2016). For each brand of car sold in the United States, data on a quality rating (defects per 100 cars, so lower numbers indicate higher quality) and a customer satisfaction rating (called the APEAL rating) are given in the accompanying table. The APEAL rating is a score between O and 1000, with higher values indicating greater satisfaction.

A warehouse manager wants to know if there is an association between the shift worked and being on time for work. To investigate, he selects a random sample of 70 workers and classifies each one according to the shift they worked most recently and whether they were on time for work. He was unable to classify a substantial number of people as being on time, so he classified those individuals as unknown. The data are displayed in the table. The manager would like to know if these data provide convincing evidence of an association between the shift worked and being on time in the large population of all workers at this warehouse. The random and 10% conditions are met. Is the Large Counts condition met? Yes, the smallest expected count is 5, so all expected counts are at least 5. Yes, the smallest expected count is 8.54, so all expected counts are at least 5. No, the smallest expected count is 2.56, so the expected counts are not all at least 5. No, the smallest expected count is…
The effects of social skill training on a 29 year-old mentally retarded male adult were explored. The subject listened to typical social situations (such as getting a compliment or saying thank you) on audiotape and discussed the situations with a therapist. The subject's positive social verbal interactions were counted before the training, at three times during the training period, and at three times after the training had been completed. All counts were taken by observing the subject at a evening recreation time in the subject's group home. Results show that positive interactions increased during the training period but then rapidly decreased after training had stopped.

February 12, 2009 marked the 20oth anniversary of Charles Darwin's birth. To celebrate, Gallup, a national polling organization, surveyed 1,018 randomly selected American adults about their education level and their beliefs about the theory of evolution. In their sample, 325 of their respondents had some college education and 228 were college graduates. Among the 325 respondents with some college education, 133 said that they believed in the theory of evolution. Among the 228 respondents who were college graduates, 121 said that they believed in the theory of evolution. Construct a 90% confidence interval for the difference between the proportions of college graduates and individuals with some college who believe in the theory of evolution.

ific Calculator Of30shg/ckivdfk1p00003g5tgeftOid1 Agroup of researchers in New York wants to test if there is any relationship between living in California and preferring warm weather to cold weather. The researchers send out an online questionnaire to 200 randomly chosen people in the US asking several questions including: "Do you live in California?" and "Do you prefer warm weather to cold weather?". The results are summarized in the table below: Prefers Warm Weather 80 Prefers Cold Weather 42 Lives in California Doesn't Live in California 35 43 Test the null hypothesis that the choices on these two questions are independent versus the alternative that they are dependent.

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 311311 people over the age of 55, 6060 dream in black and white, and among 306306 people under the age of 25, 1212 dream in black and white. Use a 0.050.05 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25.
