Giving 2. suppose that a frequency histogram and a cumulative frequency histogram are constructed from the same set of data, using the same classes. then, for each class,
(2 points)
the frequency is less than the cumulative frequency.
the frequency is less than or equal to the cumulative frequency.
the frequency is equal to the cumulative frequency.
the frequency is greater than the cumulative frequency.
the frequency is greater than or equal to the cumulative frequency.

Assume that females have pulse rates that are normally distributed with a mean of mu equals 72.0 beats per minute and a standard deviation of sigma equals 12.5 beats per minute. complete parts (a) through (c) below. a. if 1 adult female is randomly selected, find the probability that her pulse rate is between 65 beats per minute and 79 beats per minute. the probability is? b. if 16 adult females are randomly selected, find the probability that they have pulse rates with a mean between 65 beats per minute and 79 beats per minute. the probability is? c. why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
