A brisk walk at 4 miles per hour burns an average of 280 calories per hour. If the standard deviation of the distribution is 5 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...
