Amy had a beautiful plant. The plant began sprouting two days before Amy bought it, and she had it for 98 days before it died. At its tallest, the plant was 30 centimeters tall. Let h(t) denote the height of Amy’s plant h (measured in centimeters), t days from the time she bought it. Define the Domain in interval notation.

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?
