The average adult male heights in the US is 70 inches with a standard deviation of 3.3 inches. Suppose that the adult male heights closely follow a normal distribution. What is the probability that a randomly selected adult male in the US is between 69 inches and 74 inches?
And the average height for adult women in the United States is about 65 inches , with a standard deviation of around 2.5 inches. Using the mean and standard deviation that correspond to your gender (female), determine the z-score for your height, then use the z-table or technology to determine the percentage of people who are shorter than you.

The following is a random sample of 9 men from the city: { 176.2 , 157.9 , 160.1 , 180.9 , 165.1 , 167.2 , 162.9 , 155.7 , 166.2 } a) Is there enough evidence to reject the null hypothesis at a significance level α ...
A researcher compares the height of male executives in the U.S. to the average height of males (μ = 67 inches). He determines that the average height of male executives is 70 inches (95% confidence interval [CI] 68-72). Based on this result, what would the decision have been for a hypothesis test? A) Reject the null hypothesis. B) Retain the null
