Step 1

The values missed in the table will be obtained as given below:

**(a)**

Step 2

**(b)**

**The number of observation in Sample 2:**

Step 3

**(c)**

**Standard error of the difference between two proportions ( p-hat 1 – p-hat 2):**

Here, *p-*hat1 = 0.6601, *n*1 = 153, *p-*hat 2 = 0.5444, *n*2 = 90.

Denote the population proportion as *p*.

The standard error of the difference between two proportions (*p-*hat 1 – *p-*hat 2)is obtained from the calculation given below:

The test statistic is given by,
