Consider the following hypothetical situation. Grade data indicat4es that on the average 27% of the students in senior engineering classes have received A grades. From past data we have measured a standard deviation of 15%. We would like to model the proportion X of A grades with a continuous distribution. a. Which distribution should be used? Please also provide the values of the parameters. b. Use the distribution in (a) to find the probability that more than 32% of the students had an A.
