Expert Solution

Step 1

Given :

$s a m p l e s i z e (n) = 6963 X = n u m b e r o f s u r v e y s r e t u r n e d = 1313$

Here we use normal distribution as an approximation to the binomial distribution

$p = \frac{X}{n} = \frac{1313}{6963} = 0.1885 p = 0.1885 P = 0.2 Q = 1 - P = 1 - 0.2 = 0.8 Q = 0.8$

Step 2

The null hypothesis and alternative hypothesis is given by ,

$H_{0} : p = 0.2 V / S H_{1} : p < 0.2$

Answer : Option D.

$H_{0} : p = 0.2 V / S H_{1} : p < 0.2$
