Answer:

The calculated value Z=1.2413 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

An instructor in the English department at CBC believes rates at CBC may be equal to the state average

Step-by-step explanation:

Step(i):-

Given Population proportion

P=68%= 0.68

Sample proportion

$p^{-} =\frac{x}{n} = \frac{179}{250} = 0.716$

Null hypothesis : H₀ : p = 0.68

Alternative Hypothesis :H₁ : p > 0.68

Step(ii):-

Test statistic

$Z = \frac{p^{-}-P }{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.716-0.68 }{\sqrt{\frac{0.68 X 0.32}{250} } }$

Z = 1.2413

Level of significance

$Z_{0.05} = 1.96$

The calculated value Z=1.2413 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

An instructor in the English department at CBC believes rates at CBC may be equal to the state average
