For each of the following values, use the one-tail five percent (5%) criteria and determine if the occurrence of the score would be considered relatively likely or unlikely? (Note: Assume that the researcher is only interested in the extreme high percentages of students receiving free or reduced lunch--or the positive end of the normal curve). The mean is 43.45. The Standard Deviation is 17.55. Are the below answers correct?

a.86

(Z=86-43.45/17.55

=2.42

2.42 = 49.22% unlikely) area within parenthesis is my answer for each a, b, and c

b.28

(Z=28-43.45/17.55

= -0.88

-0.88 = 31.06% likely)

b.88

(Z= 88-43.45/17.55

= 2.54

2.54 = 49.45% unlikely)
