Show me the steps to solve A student named Eric is worried that he failed his Economics exam. The professor told him that the bottom 5% of the class will receive a failing grade. Eric found out that the mean of the class grades on the exam was 78 and the standard deviation was 7. Setting his sights as low as possible, what is the lowest grade Eric can receive and still pass the exam?

A Statistics teacher decides to give A's only to students who score in the top 15% on the final exam. The scores are normally distributed with a mean of 78 and a standard deviation of 7 (this is also the population standard deviation). To the nearest integer value, what is the lowest score a student could earn and still receive an A? (Please show work) A. 79 B. 80 C. 82 D. 83 E. 85

An economics professor decides to curve the grades of his class. In doing so, he decides to make it such that the students who score in the top 7% receive an A. Assume a normal distribution among grades. How many standard deviations above the mean must a student get to receive an A?

An analysis of the final test scores in this class shows that the scores follow the normal distribution. The mean of the distribution is 85 and the standard deviation is 7. The professor wants to award an A student whose score is in the highest 9% which means 91% of the class will have lower grades. What is the cut-off point (or score) for those students who earn an A versus those that earn a B? In other words, what is the lowest grade an A student can earn? Hint: solve for “x”
