Answer:

The correct option is a

Step-by-step explanation:

From the question we are told that

The sample size is n = 415

The sample proportion is $\r p = 0.49$

Now

The null hypothesis is $H_o : p = 0.3$

The alternative hypothesis is $H_a : p \ne 0.3$

The test statistics is mathematically evaluated as

$t = \frac{\r p - p }{ \frac{\sqrt{ p (1- p )} }{n} }$

substituting values

$t = \frac{0.49 - 0.3 }{ \sqrt{ \frac{0.3 (1- 0.3 ) }{415} }}$

$t = 8.446$
