About 13% of the population has blue eyes. 1700 people are randomly selected. a. Find the mean number of people with the blue eyes in such groups of 1700. b Find the standard deviation for the number of people with blue eyes in such groups of 1700. If possible, round to 1 decimal place.

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.

A coach is interested in how many slam dunks the average college freshman at his university can do. Ten volunteers from the senior class step forward. After observing their performance, the coach concluded that college seniors can do an average of 10 slam dunks in a row without missing. what is the sample? what is the population?

This is a standard deviation contest. You must choose four numbers from the whole numbers 0 to 9, with repeats allowed. Choose four numbers that have the smallest possible standard deviation. Chose four numbers that have the largest possible standard deviation. Is more than one choice correct in either? Explain.
