A shipping company claims that 95% of packages are delivered on time. A student wants to conduct asimulation to estimate the number of packages that would need to be randomly selected to find a packagethat was not delivered on time. The student assigns the digits to the outcomes.00-04 = package not delivered on time05-99 = package delivered on timeHere is a portion of a random number table.Table of Random Digits1 31640 43495 96193 10898 88532 738692 67940 85019 98036 98252 43838 456443 21805 26727 73239 53929 42564 170804 03648 93116 98590 10083 89116 502205 71716 46584 35453 98153 07062 95864Beginning at line 1, carry out one trial of this simulation.

A manufacturing company that produces laminate for countertops is interested in studying the relationship between the number of hours of training that an employee receives and the number of defects per countertop produced. Ten employees are randomly selected. The number of hours of training each employee has received is recorded and the number of defects on the most recent countertop produced is determined. The results are as follows. Hours of Training Defects per Countertop 1 5 4 1 7 0 3 3 2 5 2 4 5 1 5 2 1 8 6 2 Copy Data The estimated regression line and the standard error are given. Defects per Countertop=6.717822−1.004950(Hours of Training)se=1.229787se=1.229787 Suppose a new employee has had 5 hours of training. What would be the 90% prediction interval for the number of defects per countertop? Round your answer to two decimal places.
Race organizers want to survey the participating runners on the quality of the running course. Which of the following uses systematic random sampling? Select the first 15 finishers and the last 15 finishers to take the survey. Randomly select 15% of the male participants and 15% of the female participants. Select the 5th finisher (with the number 5 being randomly chosen) to survey, then survey every 15th finisher after that. Sort all of the runners' names alphabetically, then randomly choose 2 letters and survey all participants whose last name begins with one of those letters.
