Is a measure of 25 inches "far away" from a mean of 16 inches? As someone with knowledge of statistics, you answer "it depends" and request the standard deviation of the underlying data.
(a) Suppose the data come from a sample whose standard deviation is 3 inches. How many standard deviations is 25 inches from 16 inches?
(b) Is 25 inches far away from a mean of 16 inches?
(c) Suppose the standard deviation of the underlying data is 7 inches. Is 25 inches far away from a mean of 16 inches?
(a) 25 inches is _____standard deviation(s) away from 16 inches.
(Type an integer or decimal rounded to one decimal place as needed.)

Height data, collected from a statistics class, has a mean, X = 68.21 inches, and a standard deviation of s=4.01 inches. The sample size of the data was n = 36. Suppose the data collected could be considered a random sample of WCU students. Calculate the lower boundary of a 99% confidence z-interval. Give your answer as a decimal number rounded to 2 decimal places. INinto nu can use the calculator to find this solution or do this by hand)...
In Country A, the population mean height for 3-year-old boys is 39 inches. Suppose a random sample of 15 3-year-old boys from Country B showed a sample mean of 38.4 inches with a standard deviation of 4 inches. The boys were independently sampled. Assume that heights are Normally distributed in the population. Complete parts a through c below. Find the p-value. p equals____? (Type an integer or decimal rounded to three decimal places as needed.

How many standard deviations is his height above the mean? The player's height is nothing standard deviation(s) above the mean. (Round to two decimal places as needed.)
a. You measure 43 watermelons' weights, and find they have a mean weight of 48 ounces. Assume the population standard deviation is 2.2 ounces. Based on this, what is the maximal margin of error associated with a 95% confidence interval for the true population mean watermelon weight? Give your answer as a decimal, to two places ± ounces b. You measure 25 watermelons' weights and find they have a mean weight of 44 ounces. Assume the population standard deviation is...
