Using the Central Limit Theorem. In Exercises 5-10, use this information about the overhead reach distances...
Use the following information about the overhead reach distances of adult females: μ = 205.5cm, σ =8.6 cm, and overhead reach distances are normally distributed (based on data from the Federal Aviation Administration). The overhead reach distances are used in planning assembly work stations. Find the probability that an adult female has an overhead reach greater than 215 cm.
Use the following information about the overhead reach distances of adult females: ? = 205.5cm, ?=8.6 cm, and overhead reach distances are normally distributed. A random sample of 50 adult females is selected. Find the probability that the mean overhead reach of the sample is between 185 cm and 220 cm.
The overhead reach distances of adult females are normally distributed with a mean of 205.5 cm and a standard deviation of 8.9 cm. a. Find the probability that an individual distance is greater than 215.50 cm. b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00 cm. c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?

For #4-5, use the following information: Overhead reach
distances X are used in planning assembly workstations. The
overhead reach distance of adult females is assumed to be X ~ N
(202.5 cm, 8.0 cm) where cm refers to centimeters.
4. If 1 adult female is randomly selected, find the probability
that her overhead reach is between 194.5 cm and 210.5 cm. Use the
graph to sketch the probability as the area under the pdf
given.
5. If 64 adult females...
