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.

Let x represent the number of registered boats and let y represent the corresponding number of manatee deaths. Use the given number of registered boats and the given confidence level to construct a prediction interval estimate of manatee deaths. Use x=81(for 810,000registered boats) with a 99%confidence level. Use the chart above ___manatees<y< ___manatee

For each of the possible sample sizes, find the probability that the sampling error made in estimating the population mean by the sample mean will be 0.5 or less (in magnitude), that is, that the absolute value of the difference between the sample mean and the population mean is at most 0.5. n 1 2 3 Probability (Type integers or simplified fractions.)
The purpose and intent of the assignment is to help you better understand the sampling distribution of the mean. The class sampling exercise In class we conducted a sampling exercise. The population consisted of 25 elements. The possible values for the elements in the population ranged from 1 to 9 and were distributed as follows: Value Frequency Proportion Percentage 1 1 0.04 4% 2 2 0.08 8% 3 3 0.12 12% 4 4 0.16 16% 5 5 0.2 20% 6 4 0.16 16% 7 3 0.12 12% 8 2 0.08 8% 9 1 0.04 4% As in the class exercise, 10 elements are drawn replacing each element before the next is drawn. This was done 1000 times. The data set is given in a separate…

A research group is interested in the relationship between alcohol consumption and heart disease in American men over the age of 40 years old. The researchers randomly selected 1913 medical records of men who suffer from heart disease. The researchers reco did not drink, drank moderately, or drank heavily. They found that men who had heart disease tended to drink heavily. Identify the population for the study. Identify the sample for the study. or the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
