Expert Solution
Step 1: Given Information

The given information is as below:

The level of significance is text α end text equals 0.05.

The hypothesis to be tested for population proportion is;

text H end text subscript 0 colon text P end text equals 0.68 space space space text  v/s end text space space space space space text H end text subscript 1 colon text P end text not equal to 0.68

The sample size text n end text equals 624.

Number of successful observations, text X end text equals 393.
