(a) Use a calculator with mean and standard deviation keys to verify that the sample mean is x = 5.63 pups with the sample standard deviation s = 1.78 pups.
(b) Find a 75% confidence interval for the population mean number of wolf pups per den in the southwestern United States.
Assume the population standard deviations are not the same. At the .05 significance level, is there a difference in the mean waiting time?
Using the data file below, construct a histogram and a frequency polygon. Describe the shape of this distribution.
The conservative degrees of freedom for the t distribution are and The standard error, conservative degrees of freedom
Given length an athlete throws a hammer is a normal random variable with mean 50 feet and standard deviation five feet, what is the probability he throws it: Between 50 feet and 60 feet.

Build a scatter plot, Find the value of the linear correlation coefficient r, and find the critical value of r using α=0.05. Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables.
Suppose you had flipped a fair coin 19 times and "tails" had come up each time. The probability of now tossing a "head" on the 20th flip would then be:
