The overhead reach distances of adult females are normally distributed with a mean of 197.5cm and a standard deviation of 8.3 cm . a. Find the probability that an individual distance is greater than 210.90 cm.
b. Find the probability that the mean for 15 randomly selected distances is greater than 195.30 cm.
c. Why can the normal distribution be used in part​ (b), even though the sample size does not exceed​ 30?

idk lol

step-by-step explanation:

hm let me think hm think think hm think yes

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
