About 4% of the population has a particular genetic mutation. 600 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 600. Submit Question

Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 67.0 beats per minute. Four of the pulse rates are 54, 82, 53, and 90. a. Find the missing value. b. Suppose that you need to create a list of n values that have a specific known mean. Some of the n values can be freely selected. How many of the n values can be freely assigned before the remaining values are determined? (The result is referred to as the number of degrees of freedom.) a. The missing value is beats per minute. (Type an integer or a decimal. Do not round.)

Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 70.4 beats per minute. Four of the pulse rates are 83, 75, 91, and 51. a. Find the missing value. b. Suppose that you need to create a list of n values that have a specific known mean. Some of the n values can be freely selected. How many of then values can be freely as beats per minute. a. The missing value is (Type an integer or a decimal. Do not round.) b. Select the correct choice below and fill in the answer box to complete your choice. (Type an expression using n as the variable.) O A. Of the n values, can be freely selected because the remaining value(s) must be equal to the known mean. O B. Of then values, can be freely selected because the remaining value(s) can be expressed in terms of the mean, median, and midrange of the assigned values. O C. Of then values, can be freely selected because the remaining value(s) can be expressed in terms of the assigned values and the known…

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.
