Assume that women's heights are normally distributed with a mean given by mu equals 63.2 in, and a standard deviation given by
sigma equals 2.1 in. complete parts a and
b.
a. if 1 woman is randomly selected, find the probability that her height is between 62.4 in and 63.4 in. the probability is approximately . 1863. (round to four decimal places as needed.)
b. if 7 women are randomly selected, find the probability that they have a mean height between 62.4 in and 63.4 in

Answer:
For the first 30 minutes, we will have a line with a given steepness, this will represent the 30 minutes riding at a fast pace.
Then he stops for 20 minutes, we will represent this with a constant line.
Then he again moves for another 30 minutes, but with a slower pace than in the first 30 minutes, then this line will be less steep than the first line.
A sketch of this situation can be seen below.
