The overhead reach distances of adult females are normally distributed with a mean of 205.5 cm and a standard deviation of 8.3 cm. a. find the probability that an individual distance is greater than 218.90 cm. b. find the probability that the mean for 20 randomly selected distances is greater than 204.20 cm. c. why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
