The public school system in a certain county has a special, free remedial reading program for it's 4'th grade students who score in the lowest 4% of reading ability at that grade level. Let "R" represent a 4'th grade student's reading score. R ~ N(450,625)
Hint: I know you guys hate to do this because you think it's a waste of your time but y'all should really draw an appropriate diagram
Note: Round all answers to the nearest integer.
A) The maximum reading score a student can have and still qualify for this free remedial program is:
B) Students in the top 1.75% are qualified to be peer mentors. The minimum score necessary for a 4'th grade student to be considered for a peer mentor position is

A) x = z*(sigma) + mu = -1.75(25) + 450 = 406.23
B) x = z*(sigma) + mu = +1.75(25) + 450 = 493.75
(the 1.75's come from the z-table that correspond to 4%)
B) x = z*(sigma) + mu = +1.75(25) + 450 = 493.75
