About 9% of the population has a particular genetic mutation. 800 people are randomly selected. Find the standard deviation for the number of people with the genetic mutation in such groups of 800. Round your answer to three decimal places

Determine whether each sample is a random sample or a biased sample. Explain. 1. Carlos chooses 50 movies at random from a list of all his movies to determine the average runtime of the movies in his collection.

Find the mean and stand deviation for each sample. sample A 5,11,17 sample B 77,82,88 sample C 1,075,1,081,1,087

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.)

Find the standard deviation. Group 1: 7,8,7,6,7,7,7

The ages for a sample of fans at a concert are listed. Whats the mean, median, mode, range, variance, standard deviation, and coefficient of variation?

Find the range, the standard deviation, and the variance for the given samples. Round non-integer results to the nearest tenth. 75, 58, 61, 63, 48, 96, 49, 82, 97

The length of time a particular smartphone's battery lasts follows an exponential distribution with a mean of ten months. A sample of 64 of these smartphones is taken. What is the distribution for the total length of time 64 batteries last? (Enter exact numbers as integers, fractions, or decimals.) X - ? v Additional Materials eBook

Carmen and Rosanna are two employees in an electronics store. The store manager has put an emphasis on increasing the number of applications for the store credit card. The manager randomly selected 24 weeks for each employee and recorded the number of completed applications for each week, which is provided in the samples below. Each employee completed 21 applications in one of the weeks selected. Use Excel to calculate each employee's z-score for completing 21 applications. Round your answers to two decimal places.

Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 68.6 beats per minute. Four of the pulse rates are 74, 70, 51, and 93. 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 i 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.) b. Select the correct choice below and fill in the answer box to complete your choice. (Type an expression using n as the variable.) OA. Of the n values, OB. Of the n values, O C. Of the n values, (...) can be freely selected because the remaining value(s) can be expressed in terms of the assigned values and the known mean. can be freely selected because the remaining value(s) can be expressed in terms of the mean,…
