Please solve this stat equation

7. (Show your Work!) At some high school, the students are given z-scores at the end of each semester, rather than traditional GPA's. The mean and standard deviation of all students' GPA's, on which the z-scores are based, are 2.85 and 0.42. Complete parts a. and b. using the appropriate probability table. (Assume the distribution is Normal) a. The lowest 4% of student GPA's will require teacher conferences with the students' parent(s). What is the corresponding GPA for when a student teacher conference is required?(Round to two decimal places as needed) b. The principle of the high school wishes to graduate students with GPA's 3.7 and above with high honors. What proportion of students would qualify for high honors? (Round to four decimal places as needed)
