- The average grade for an exam is 74, and the standard deviation is 7. If 11.9% of the class is given A’s (including A-, A, and A+), and the grades follow a normal distribution, what is the lowest possible grade for an A- and what is the highest possible grade for a B+? We assume that the numerical grades the students receive are always integers. Answer using z tables.Find the variance of the binomial distribution for which n=800 and p=0.93.

- A standardized exam's scores are normally distributed. In a recent year, the mean test score was 21.1 and the standard deviation was 5.7. The test scores of four students selected at random are 14, 22, 7, and 35. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The z-score for 14 is (Round to two decimal places as needed.) The z-score for 22 is (Round to two decimal places as needed.) The z-score for 7 is (Round to two decimal places as needed.) The z-score for 35 is (Round to two decimal places as needed.) Which values, if any, are unusual? Select the correct choice below and, if necessary, fill in the answer box within your choice. O A. The unusual value(s) is/are (Use a comma to separate answers as needed.) O B.
