A brisk walk at 4 miles per hour burns an average of 290 calories per hour. If the standard deviation of the distribution is 9 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. Round the probability answers to three decimal places. Refer to the table of values (Area Under the Standard Normal Distribution) as needed. Part: 0/3 Part 1 of 3 (a) More than 263 calories The probability that a randomly selected person burns more than 263 calories is X S
