Select the two correct answers. The median upload speed during peak hours is 5.905 megabits per second, which is less than the median upload speed during off-peak hours, 7.005 megabits per second. The upload speeds during peak hours are slower on average compared to off-peak times. The median upload speed during peak hours is 6.37 megabits per second, which is greater than the median upload speed during…John Kittle, an independent insurance agent, uses a five-year moving average to forecast the number of claims made in a single year for one of the large insurance companies he sells for. He has just discovered that a clerk in his employ incorrectly entered the number of claims made four years ago as 1,400 when it should have been 1,200.a. What adjustment should Mr. Kittle make in next year’s forecast to take into account the corrected value of the number of claims four years ago?b. Suppose that Mr. Kittle used simple exponential smoothing with a = .2instead of moving averages to determine his forecast. What adjustment is now required in next year’s forecast? (Note that you do not need to know the value of the forecast for next year in order to solve this problem.)A local gas station has developed a new lottery scratch card in which they want 20% of contestants to win a small prize, 5% of contestants to win a medium prize, and 1% of contestants to win a large prize.

Assuming college requires five years, show that the annual return to each year of college education averages 10.9 percent. b. It is typically thought that this type of calculation of the returns to schooling is biased because it doesn’t take into account innate ability (i.e., ability in the workplace not due to college) or innate motivation. If this criticism is true, is the actual return to each year of a college education more than or less than 10.9 percent?Calculateaconfidenceinterval for the me-dian ofthe second population.Select your confidenc eleve land reportit with your answer.??
