Step 6 (c) Let us assume that x has a distribution that is approximately normal. What is the probability that x is between $35 and $39? If we assume the x distribution is approximately normal, we will convert the x values in the given interval P(35 ≤ x ≤ 39) to z scores, but instead of using the standard error ox, we can use the standard deviation of x, o = 9. Use the standard deviation and the given mean μ = 37 to calculate the z score corresponding to x = 35, rounding the result to two decimal places. x-μ Z = 0 35 = 0.2 Z = x-μ Calculate the z-score corresponding to x = 39, rounding the result to two decimal places. 0 39 Submit = 0.2 9 X 9 - 37 X 37 Skip (you cannot come back)
