Based on past studies, you can assume that the standard deviation for the population for their maturity period is 15 days. You have been asked to determine a 95% two-sided confidence interval for the overall gestation period in the population. What would alpha be for this calculation (to 2 decimal places)? Answer: What value would you use for Z in this calculation (to 2 decimal places)? Answer: What would be the margin of error (E) for the confidence interval (to 2 decimal places)?

You are curious if the proportion of OU college students 8 9 10 11 12 playing video games at that level is similar to the national average, so you survey 80 students Points out of and find out that 55 of them are playing video games more than 20 hours a week. You decide 13 14 15 16 17 18 1.00 to set up a hypothesis test to determine whether the proportion of OU students playing games Flag at that level each week is similar to the national average. You will run your test using at a 95% 19 20 21 22 23 24 question confidence level (alpha = 0.05). 25 What would be the correct set of hypotheses to use for this test? Finish attempt ... O a.
