Answer:
Required probability is 0.9748
Step-by-step explanation:
given data
mean = 117.7-cm
standard deviation = 2.2-cm
sample size n = 29
solution
we consider here random variable which represents here length of rod= x
so get here first z that is express as
put here value with x value 118.5-cm
Z = 1.9582
p value is 0.9748
so required probability is 0.9748

The first-serve percentage of a
tennis player in a match is normally distributed with a standard deviation of

mean is 83.71%.
