6. The resting pulse rate, X, for a particular population of adult women is normally distributed wmean of 74 beats per minute (bpm) and a standard deviation of 6 bpm.a) Find P(66 s X s 78)b) Find the 60th percentile of women's resting heart rates.c) If a sample of four women is randomly selected, find P(X > 79).d) Suppose now that the sample size is greater than four. Will the probability P(X > 79)be greater than, less than or the same as the value found in part c)? Explain.

A standardized exam’s score are normally distributed. In a recent year, the mean test score was 1477 and the standard was 315. The test scores of four students selected at random 1860 1230, 2160, and 1360. Find the Z- score that correspond to each value and determine wether any of the values are unusual. The Z-score for 1860 is-The Z-score for 1230 is-The Z-score for 2160 is-The Z-score for 1360is-
The mean total cholesterol for a population of men between the ages of 20 and 29 is 180 micrograms per decilitre with a standard deviation of 37.4. A healthy total cholesterol level is less than 200, 200-240 is border line, and above 240 is dangerous. Assume the distribution is approximately Normal. For a randomly selected man from this group, what is the probability that his total cholesterol level is i. 200 or more? 1i. Between 200 and 240?

Scores on a standardized exam are known to follow a normal distribution with standard deviation σ = 21. A researcher randomly selects 125 students and computes their average score. He reports that the mean score is 73.8, with a margin of error of 2.920. How confident are you that the mean score for all students taking the exam is in the interval (70.88, 76.72)?
