a. State the hypothesesAccording to the College Board report 58.7% student score more that 3 or higher.
Thus Null hypothesis H0: p = 0.587
Alternative Hypothesis H1: p > 0.587
Alpha level = 0.05
b. State the formula and find the test statistics. (TI- 84 calculator may be useful)
Since np = 34*0.587 = 19.958 > 5 and n (1-p) = 34*(1- 0.587) = 14.042 > 5
This shows that data is normally distributed. According to the problem 34 student score 3 or better.
thus p^ = 34/54 = 0.630 (approx)...
