Sample proportion = 75/100 = 0.75
Test statistics
z = - p / sqrt(p(1-p) / n)
= 0.75 - 0.6 / sqrt( 0.6 * 0.4 / 100)
= 3.06
a)
Critical value at 0.05 level is 1.645
Reject the null hypothesis.because test statistics is greater than critical value.
b)
p-value = P(Z > z)
= P( Z > 3.06)
= 0.0011
Reject the null hypothesis because p-value is less than
