Question 33, 5.2.24-E Question Help Assume that when adults with smartphones are randomly selected, 49% use them in meetings or classes. If 12 adult smartphone users are randomly selected, find the probability that fewer than 5 of them use their smartphones in meetings or classes. The probability is (Type an integer or decimal rounded to four decimal places as needed.)Question 38, 6.1. 11-T Question Help Find the area of the shaded region. The graph depicts the standard normal distribution of bone density scores with mean 0 and standard deviation 1. z= - 0.88 z = 1.22 The area of the shaded region is (Round to four decimal places as needed.)Question 46, 6.4.5-T Question Help Assume that females have pulse rates that are normally distributed with a mean of u = 74.0 beats per minute and a standard deviation of o = 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 less than 80 beats per minute. The probability is (Round to four decimal places as needed.)Question 47, 6.4.6-T Question Helpv at The overhead reach distances of adult females are normally distributed With a mean of 197.5 cm and a standard deVIation of 8.9 cm. a. Find the probability that an individual distance is greater than 20750 cm b. Find the probability that the mean for 25 randomly selected distances is greater than 196 00 cm, 1:. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30'? a.
