Resistance training is a popular form of conditioning aimed at enhancing sports performance and is widely used among highschool, college, and professional athletes, although its use for younger athletes is controversial. A random sample of 4111patients between the ages of 8 and 30 admitted to U.S. emergency rooms with the injury code "weightlifting" was obtained.These injuries were classified as "accidental" if caused by dropped weight or improper equipment use. The patients were alsoclassified into the four age categories 8–13 years, 14–18, 19–22, and 23–30.A two-way table of the results is given.AgeAccidentalNot accidental8-1329510214–1865591619–2223953323-303631008Compare the distributions of ages for accidental and nonaccidental injuries.

A company uses an automated process in checking for defective electronic devices that they manufacture. For devices that are defective, 98% of them will be labeled as defective. Three percent of the devices that are okay (not defective) will be labeled as defective. Four percent of the devices made by this company are defective. _____________________ percent of devices that are labeled as defective are not defective.
Childhood obesity: A national health survey weighed a sample of 535 boys aged 6 - 11 and found that 83 of them were overweight. They weighed a sample of 474 girls aged 6 - 11 and found that 70 of them were overweight. Can you conclude that the proportion of boys who are overweight is greater than the proportion of girls who are overweight? Let p1 denote the proportion of boys who are overweight and let p2 denote the proportion of girls who are overweight. Use the =α0.05 level of significance and the critical value method with the table. (a) State the appropriate null and alternate hypotheses. (b) Compute the value of the test statistic. (c) State a conclusion at the =α0.05 level of significance.
In 2016 the Better Business Bureau settled 84% of complaints they received in the United States. Suppose you have been hired by the Better Business Bureau to investigate the complaints they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the Better Business Bureau is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.84, the same as the overall proportion of complaints settled in 2016. Use the z-table. a. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of p. E(p) (to 2 decimals) (to 4 decimals) b. Based upon a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion (to 4 decimals)? probability : = c. Suppose you select a sample of 460 complaints involving new car dealers. Show the sampling distribution of p. E(F) (to 2…

R3.23. Tips In restaurants, servers rely on tips as a major source of income. Does serving candy after the meal produce larger tips? To find out, two waiters determined randomly whether or not to give candy to 92 dining parties. They recorded the sizes of the tips and reported that guests getting candy tipped an average of 17.8% of the bill, compared with an average tip of only 15.1% from those who got no candy. ("Sweetening the Till: The Use of Candy to Increase Restaurant Tipping," Journal of Applied Social Psychology 32, no. 2 [2002]: 300-309) a) Was this an experiment or an observational study? Explain. b) Is it reasonable to conclude that the candy caused guests to tip more? Explain. c) The researchers said the difference was statistically sig- nificant. Explain in this context what that means.

Español A decade-old study found that the proportion, p, of high school seniors who believed that "getting rich" was an important personal goal was 80%. A researcher decides to test whether or not that percentage still stands. He finds that, among the 240 high school seniors in his random sample, 185 believe that "getting rich" is an important goal. Can he conclude, at the 0.10 level of significance, that the proportion has indeed changed? Perform a two-tailed test. Then complete the parts below.
