About 3% of the population has a particular genetic mutation. 400 people are randomly selected. Find the standard deviation for the number of people with the genetic mutation in such groups

105, 82, 94.5, 72.5, 92, 91, 52, 86, 100, 96, 98, 109, 96, 36, 98, 95

Add 7 to every output x. What happens to the mean and the variance? What are the new sample mean, the new expected mean, and the new variance?

Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 68.8 beats per minute. Four of the pulse rates are 95​, 64, 50​, and 57. 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.

About 7% of the population has a particular genetic mutation. 100 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 100. (Round to 2 decimal places if possible.)

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 76.6 beats per minute. Four of the pulse rates are 82, 59, 84, and 89. 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.)

Sixty-three percent of U.S. households have a personal computer. In a random sample of 400 households, determine the mean of the binomial distribution.

About 10% of the population has a particular genetic mutation. 300 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 300. (Round to 2 decimal places if possible.)
