Need help solving. With the explanation I need to understand the function used in the calculator, please.

1. According to medical research, the mean resting pulse rate for adult women in the United States is 74 beats per minute (bpm) and the standard deviation is 13 bpm. The distribution for this population is skewed right. Suppose that a cardiologist takes a random sample of 64 women from the United States.

A) Assume this sample satisfies CLT. Draw a picture of the sample distribution below. (Keep in mind the sample distribution will not have a standard deviation of 13!)

B) What is the probability that the sample mean resting pulse rate is less than 72 bpm? (Write down what you type into the calculator to calculate this). Draw a picture and shade the area that shows this probability.

C) Suppose that the mean resting pulse rate for a sample this size is = 79 bpm; is that unusual? Explain using complete sentences.

D) Suppose that the sample size decreases. What will happen to the standard error of this sample distribution?
