Since an instant replay system for tennis was introduced at a major tournament, men challenged 1408 referee calls, with the result that 411 of the calls were overturned. Women challenged 743 referee calls, and 217 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

According to a Pew Research Center nationwide telephone survey of American adults conducted by phone between March 15 and April 24, 2011, 75% of adults said that college education has become too expensive for most people and they cannot afford it (Time, May 30, 2011). Suppose that this result is true for the 2011 population of American adults. In a recent poll of 1570 American adults, 1160 said that college education has become too expensive for most people and they cannot afford it. Using a 1% significance level, perform a test of hypothesis to determine whether the current percentage of American adults who will say that college education has become too expensive for most people and they cannot afford it is lower than 75%. Use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places. Zobserved = %3D p-value = Critical value = We can conclude that the…

Chick-fil-A gets it right. Which fast-food chain fills orders most accurately at the drive-thru window? The Quick Servcie Restaurant magazine drive-thru study involved a total of 7594 visits to restaurants in the 25 largest fast-food chains in all 50 states. All visits occured during the lunch hours of 11:00 A.M. to 2:30 P.M. or during the dinner hours of 4:00 to 7:00 P.M. During each visit, the researcher ordered a maint item, a side item, and a drink. One item was left off of each order; for example, a field researcher could order a burger with no pickles. After recieving the order, all the food and drink items were checked for accuracy. ANy food or drink item recieved that was not exactly as ordered resulted in the order being classified as inaccurate. Also included the measurement of accuracy were condiments asked for, napkins, straws, and correct change. Any errors in these resulted in the order being classified as inaccurate. Chick-fil-A had the fewest inaccuracies, with only 14…

A consumer testing agency wants to evaluate the claim made by a manufacturer of discount tires. The manufacturer claims that its tires can be driven at least 35,000 miles before wearing out. To determine the average number of miles that can be obtained from the manufacturer’s tires, the agency randomly selects 60 tires from the manufacturer’s warehouse and places the tires on 15 cars driven by test drivers on a 2-mile oval track. The number of miles driven (in thousands of miles) until the tires are determined to be worn out is given in the following table. Car 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 n y s Miles Driven 25 27 35 42 28 37 40 31 29 33 30 26 31 28 30 15 31.47 5.04 a. Place a 99% confidence interval on the average number of miles driven, m, prior to the tires wearing out. b. Is there significant evidence (a 5 .01) that the manufacturer’s claim is false? What is the level of significance of your test? Interpret your findings.

An LED light bulb manufacturer claims that the average lifespan of its 60-watt LED light bulbs is 43,000 hours.A corporate watchdog group is suspicious of the company's claim and thinks that the true average lifespan of the 60-watt LED light bulbs produced by the company may be less than the advertised 43,000 hours. The group collected and tested a random sample of 240 light bulbs and found the average lifespan of the sample was 42,958 hours.Use the p-value method to test the hypothesis that the mean lifespan of this brand of 60-watt LED light bulb is less than 43,000 hours, using α=0.025α=0.025. Assume the standard deviation of the lifespan of all such light bulbs is known to be 430 hours.State the null and alternative hypothesis for this test.H0:H0: H1:H1: Determine if this test is left-tailed, right-tailed, or two-tailed. right-tailed two-tailed left-tailed Should the standard normal (zz) distribution or Student's (tt) distribution be used for this…
