Question Suppose heights of dogs, in inches, in a city have an unknown distribution with mean 27 and standard deviation 6 inches. A sample of size n = 57 is randomly taken from the population and the sum of the values is taken. Using the Central Limit Theorem for Sums, what is the standard deviation for the sample sum distribution? • Round the final answer to two decimal places. Sorry, that's incorrect.

Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $227 with a standard deviation of $58. Random samples of size 22 are drawn from this population and the mean of each sample is determined. Question content area bottom Part 1 The mean of the distribution of sample means is enter your response here .

A Gallup poll wants to determine the mean number of books Americans read each year. How many subjects are needed to estimate the average number of books Americans read with a margin of error of 0.58 books with 80% confidence? Initial results of the Gallup poll indicate that the population standard deviation is 5.5 books. Round your answer up to the next integer. Question Help: D Video Submit Question P Type here to search
