Find the probability given p answer in the ten thousandths
Find the probability given : p = answer in the ten thousandths.
H0 : p =0.94
H1 : p > 0.94
n = 224
x = 213
If = 0.01 would we reject(r) or do not reject(dnr) the hypothesis
Solution
p = 213 / 224 = 0.95
alpha = 0.01
critical value : 2.32
we reject Ho if Z > 2.32
Z = [0.95 - 0.94 ] / [ srqt( [0.94*0.06] / 224 )]
Z = 0.01 / 0.01587
Z = 0.63
conclusion
we dont reject Ho because Z < critical value
