Step 1

The null and alternative hypotheses are as follows:

From the information, a right tail test with level of significance 0.02 is given.

Null hypothesis:

*H*_{0}: *p* = 0.47.

Alternative hypothesis:

*H*_{a}: *p* > 0.47.

From the given information, sample of size (*n*) 394 there are 214 successful observations.

Step 2

The test statistics is,

Step 3

The test statistics is (*z*) is **2.932**.

The *p*-value is:

From standard normal table, the are...
