Do Japanese managers have a different motivation level than American managers? A randomly selected group of each were administered the Sarnoff Survey of Attitudes Toward Life (SSATL), which measures motivation for upward mobility. The SSATL scores are summarized below.    American Japanese Sample Size 211 180 Sample Mean SSATL Score 65.75 79.83 Sample Std. Dev. 11.07 6.41  Given this situation, which null and alternative hypotheses to determine if the mean SSATL score of Japanese managers is greater than the mean SSATL score of American managers?

Do Japanese managers have a different motivation level than American managers?  A randomly selected group of each were administered the Sarnoff Survey of Attitudes Toward Life (SSATL), which measures motivation for upward mobility. The SSATL scores are summarized below.    American Japanese Sample Size 211 180 Sample Mean SSATL Score 65.75 79.83 Sample Std. Dev. 11.07 6.41  A two-tailed hypothesis test for the difference in means between two independent populations was conducted.  If the p value resulting from the test were .085 what would be the conclusion of the test?

For air travelers, one of the biggest complaints is of the waiting time between when the airplane taxis away from the terminal until the flight takes off. This waiting time is known to have a right skewed distribution with a mean of 10 minutes and a standard deviation of 8 minutes. Suppose 10000 flights have been randomly sampled. Describe the sampling distribution of the mean waiting time between when the airplane taxis away from the terminal until the flight takes off for these 10000 flights.

Let’s say the table below shows the proportion of all domestic phone calls in the United States split into categories of the duration of calls. Of a sample of 1000 calls, what proportion of those calls would we expect to last 30 minutes and more? Time in Minutes Proportion of All Calls 0 but less than 5 .37 5 but less than 10 .22 10 but less than 15 .15 15 but less than 20 .10 20 but less than 25 .07 25 but less than 30 .07 30 and more .02
