Question

0.4.3-1 Assume that females have pulse rates that are normally distributed with a man of 75.0 beats per minute and a standard deviation of a = 125 brats per minute. Completo parts(a) through it below a. If aut female is rondom dind the probaby that her pulse rate is less than beals per minute The probably is Round to four demanded

Answer 1

Mean =75 and standard deviation (s) = 12.5

Find p(x<78)

Normalcdf(-1e99,78,75,12.5)

=0.5948

Question 2)

Normalcdf(65,79,72,12.5)

=0.4245
