20 21 22 23 24 25 26 v 27 28 29 30 = 31 A brisk walk at 4 miles per hour burns an average of 320 calories per hour. If the standard deviation of the distribution is 7 calories, find the probability that a person who walks 1 hour at the rate of 4 miles per hour will burn the given number of calories. 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 293 calories The probability that a randomly selected person burns more than 293 calories is | 100 %. Part 2 of 3 V (b) Less than 281 calories The probability that a randomly selected person burns less than 281 calories is |0%. Part: 2 / 3 Part 3 of 3 (c) Between 308 and 340 calories The probability that a randomly selected person burns between 308 and 340 calories is 76.2 % . X Check Save For Later Submit Assic
