Researchers at Purdue University and Wichita State University found that airlines are doing a better job of getting passengers to their destinations on time.t AirTran Airways and Southwest Airlines were among the leaders in on-time arrivals with both having 88% of their flights arriving on time. But for the 12% of flights that were delayed, how many minutes were these flights late? Sample data showing the number of minutes that delayed flights were late are provided in the file named AirDelay. Data are shown for both airlines.

A governmental agency computed the proportion of violent crimes in the United States in a particular year falling into each of four olo categories. A simple random sample of 550 violent crimes committed in California during that year were categorized in the same way. The following table presents the results.

Are American men or women more into online dating? Researchers from a pop culture magazine conducted a study to see if there is a difference in the proportion of men and women under 30 that use online dating sites. They collected independent random samples of 96 women and 88 men, ranging from 18-30 years old, from across the US. Of the women, 67 reported using online dating sites, while 62 of the men reported using online dating sites. Assume the subjects responded honestly. What would be the test statistic and P-value for performing a hypothesis test Ho : P1 = P2 vs. HA : P1 + P2 ? Select one: O a. z =-0.098 ; P-value = 0.9204 O b. z =-1.13 ; P-value = 0.1292 O c. z =-3.77 ; P-value is approximately 0 O d. z =-0.098 ; P-value = 0.4602 O e. z =-1.13 ; P-value = 0.2594 Clear my choice

Rowling (1000), David Copperfield (1000), and Jerry Seinfeld (950). Find the range, variance, and standard deviation for the sample data. What do the results tell us about the population of all celebrities? Based on the nature of the amounts, what can be inferred about their precision? The range is $ million.

Are America's top chief executive officers (CEOs) really worth all that money? One way to answer this question is to look at row B, the annual company percentage increase in revenue, versus row A, the CEO's annual percentage salary increase in that same company. Suppose that a random sample of companies yielded the following data: Do these data indicate that the population mean percentage difference in corporate revenue (row B) is different from the population mean percentage increase in CEO salary? Use a 1% level of significance. (A) Are the data statistically significant at level α? Will you reject or fail to reject the null hypothesis? Since the interval containing the P-values has values that are larger than the level of significance, the data are not statistically significant and so we fail to reject the null hypothesis. (a)Since the interval containing the P-values has values that are larger than the level of significance, the data…

One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. After taking the test and seeing your score for this subsection, you're interested in the mean score, μ , among the general population on this subsection. The website reports that μ is 148 , but you believe that μ is greater than 148 . You decide to do a statistical test. You choose a random sample of people and have them take the personality test. You find that their mean score on the subsection is 152 and that the standard deviation of their scores is 28 . Based on this information, answer the questions below. What are the null hypothesis ( H0 ) and the alternative hypothesis ( H1 ) that should be used for the test? H0 : μ is H1 : μ is In the context of this test, what is a Type I error?A Type I error is the hypothesis that μ is when, in fact, μ is .Suppose that you decide not to…
