### Statistical Probability Exercise**Question 5**According to CBS Money Watch, the average monthly household cellular phone bill is $100. Suppose monthly household cell phone bills are normally distributed with a standard deviation of $11.35. What is the probability that a randomly selected monthly cell phone bill is more than $120? Round your answer to 3 decimal places. ---*Understanding the Problem:*1. **Mean (μ):** $1002. **Standard Deviation (σ):** $11.353. **Threshold Value:** $120Calculate the probability that the cell phone bill exceeds $120 using the properties of the normal distribution. To solve this problem, you would typically convert the value to a Z-score and then use standard normal distribution tables or a statistical software to find the probability.

It is given that the mean is 100 and the standard deviation is 11.35.

Answered: According to CBS Money Watch, the…
