Arandom sample of n=36 flights were taken and the time recorded to board the flight. previous studies had determined that mean time to be 40 minutes with standard deviation of 24 minutes.

a) what is the sampling distribution of the sample mean?
b) what is the probability that the average time exceeds 45 minutes?

step-by-step explanation:

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
