A survey found that people keep their televisions an average of 5.8 years. The standard deviation is 0.82 year. If a person decides to buy a new TV, find the probability that he or she owned the old one for the given amount of time. Assume the random variable is normally distributed: Refer to the table of values ( Area Under the Standard Normal Distribution) as needed. If necessary, round intermediate calculations to the nearest hundredth. Part 1 of 3 (a) More than 5.2 years The probability that a randomly selected person has owned his or her old TV for more than 5.2 years is 76.78 %. Part: 1 / 3 Part 2 of 3 (b) Less than 4 years The probability that a randomly selected person has owned his or her old TV for less than 4 years is % X
