### Financial Capability Challenge QuestionHigh school students across the nation compete in a financial capability challenge each year by taking a National Financial Capability Challenge Exam. Students who score in the top 24 percent are recognized publicly for their achievement by the Department of the Treasury. Assuming a normal distribution, how many standard deviations above the mean does a student have to score to be publicly recognized? (Round your answer to 2 decimal places.)### Answer:- **Standard deviations:** 0.02

Solve the problem. Before a new phone system was installed, the amount a company spent on personal calls followed a normal distribution with an average of $400 per month and a standard deviation of $50 per month. Refer to such expenses as PCE's (personal call expenses). Find the point in the distribution above 4.5%. Round your answer to nearest hundredth.
During a meteor shower, Hannah counts how many meteors she sees each minute. During the first 5 minutes she sees 6, 4, 10, 3, and 7 meteors. If she sees 10 meteors in the next minute, how does this affect the mean and the standard deviation of the data? Both the mean and standard deviation would increase. The mean would decrease while the standard devaition increases. O The mean would increase while the standard deviation decreases. Both the mean and standard deviation would decrease.
