Problem 05 Empirical Rule : Several years of final exam scores in statistics courses for a local university are normally distributed with a mean of 81 and a standard deviation of 8. If the lowest 2.5% of the scores on this test qualifies for a failing grade (F), use the empirical rule to calculate the score a student would need on this test to pass the final exam? show your work integer answer
Problem 08 Expected Value and Life Insurance Payouts : There is a 0.9985 probability that a randomly selected 60-year-old female lives through the year U.S. Department of Health and Human Services. A Fidelity life insurance company charges $180 for insuring that the female will live through the year. If the female does not survive the year, the policy pays out $100,000 as a death benefit.
Problem 11 Continuous Random Variables: Empirical Rule: Scores on an examination are assumed to be normally distributed with mean 78 and variance 10. Suppose that students scoring in the top 10% of this distribution are to receive an A grade. If you are asked “What is the minimum score a student must achieve to earn an A grade?”, can you use the empirical rule to answer this question? Explain your answer.

You want to test whether salaries have gone up compared to the year 2000. The 2000 Census shows that the average annual salary of all Americans was $35,152. You take an SRS of 10 Americans, ask for their annual salary for the year, and get the following results in thousands of dollars:
| Annual Salary |
| 45 |
| 16 |
| 24 |
| 83 |
| 103 |
| 31 |
| 69 |
| 94 |
| 72 |
| 20 |
A) Determine the population(s) and parameter(s) being discussed.
B) Determine which tool will help us find what we need (one sample z test, one sample t test, two sample t test, one sample z interval, one sample t interval, two sample t interval).
C) Check if the conditions for this tool hold.
D) Whether or not the conditions hold, use the tool you choose in part B. Use C=95% for all confidence intervals and alpha=5% for all significance tests.

In the MATLAB environment, display an image of a breast
mammogram from the MAMMO database. Apply gray-level scaling,
histogram equalization, and an LOG enhancement mask for image
enhancement as given below. Compare the enhanced images to original
image qualitatively.
LOG enhancement mask to be convolved with the image:
- 1 -1 -1
- 1 9 - 1
-1 -1 -1

National Artists Association (NAA) maintains a small database to track painters, paintings, and galleries. A painting is created by a particular artist and then exhibited in a particular gallery. A gallery can exhibit many paintings, but each painting can be exhibited in only one gallery. Similarly, a painting is created by a single painter, but each painter can create many paintings. Create a database implementation of the statements above using SQL.
