Question: A study examined how long aircraft air conditioning units operated after being

repaired. Here are the operating times (in hours) for one unit (Excel exam file;

worksheet Question 1):

14	38	43	48	50	63	63	73	78
82	82	87	90	95	96	101	102	118
119	132	137	138	145	156	165	169	171

Make a histogram of these data, using 40 hour wide classes, starting with
0 time < 40, 40 time < 80, ...
Describe the overall shape of the distribution. Is it roughly symmetric, skewed to the
right, or skewed to the left? Are there any outliers?
Is the five number summary or the mean and standard deviation a better brief
