Question

The company wants to know if mechanics A and B has difference in maintaining same machine. Here are the number of days until the machine has error (5 machines in total)

A	7	5	8	3	9	5
B	2	10	8	6	5	3

Do hypothesis test on if a mechanic is better than the other (no distribution assumptions).
2. Do the same hypothesis test again, but suppose the data differences are from approximately normal distribution.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
