Suppose that the amount of snowfall that Minneapolis gets in a year is normally distributed with a mean of 45 inches and a standard deviation of 5 inches. This year, what is the probability that Minneapolis will gets.
a) More than 48 inches of rain This would be 2 standard deviations or more above the mean and construct a 95 % confidence interval.
b) Between 33 and 43 inches of rain One standard deviation on either side of the mean… and construct a 90 % confidence interval.
c) Less than 23 inches of rain 3 Standard deviations or more below the mean and construct a 99 % confidence interval.

Suppose that the lengths, in inches, of adult corn snakes are normally distributed with an unknown mean and standard deviation. A random sample of 38 snakes is taken and gives a sample mean of 51 inches and a sample standard deviation of 8 inches. The margin of error, for a 95% confidence interval estimate for the population mean using the Student's t-distribution is determined to be 2.63. Find a 95% confidence interval estimate for the population means using the Student's...
