Assume that females have pulse rates that are normally distributed with a mean of mu equals 76.0 beats per minute and a standard deviation of sigma equals 12.5 beats per minute. if 4 adult females are randomly​ selected, find the probability that they have pulse rates with a mean less than 83 beats per minute.

Solution: We are given that females have pulse rates that are normally distributed with a

We have to find

First we need to determine the z score corresponding to

We know that:

Now, we have to find

Using the standard normal table, we have:

Therefore, if 4 adult females are randomly selected the probability that they have pulse rates with a mean less than 83 beats per minute is 0.8686

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
