Answer 1

25)

What is Jim's percentile rank on this project?

The sample mean and the sample standard deviation for the score is obtained in excel using the function =AVERAGE() and =STDEV(). The screenshot is shown below,

Jim's percentile is score is obtained by calculating the z score.

The probability for the z score is obtained from the standard normal distribution table,
