47 45 45 52 58 55 58 44 42 38
45 52 48 47 51 45 52 42 37 40
a. Compute the mean, median, mode, and standard deviation, Q1, Q3, Min, Max for the above sample data on age of pilots.

We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
Find the mean first = sum of scores/number of scores
Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.
Standard deviation = square root of variance
For median, Q1 and Q3, arrange scores from lowest to highest. Median = 50th percentile, Q1 = 25th and Q3 = 75th. You should also be able to define min and max once you have done your arrangement.
