Question 1 a) Suppose the scores in a certain class are normally distributed with a mean of 438 and standard deviation of 58. What is the probability a randomly selected student's score is between 402 and 509.92?Round all z scores to two decimals. Enter your final answer as a decimal to four places (e.g. 0.1234). Probabilities must match values from the table b) Suppose the scores in a certain class are normally distributed with a mean of 438 and standard deviation of 58. What is the probability a randomly selected student's score is above 555.74? Round all z scores to two decimals. Enter your final answer as a decimal to four places (e.g. 0.1234). Probabilities must match values from the table c) Suppose the scores in a certain class are normally distributed with a mean of 438 and standard deviation of 58. What is the probability a randomly selected student's score is below 528? Round all z scores to two decimals. Enter your final answer as a decimal to four places (e.g. 0.1234). Probabilities must match
