Damm [24]

Answer: p value is 0.1685.

Step-by-step explanation:

Since we have given that

The survey is conducted on a random sample of 240 pet owners.

Out of them, number of owners spoke to their pet on telephone = 79

n = 240

x = 79

$\hat{p}=\dfrac{x}{n}=\dfrac{79}{240}=0.33$

Our hypothesis would be

$H_0:p=0.5\\\\H_1:p>0.5$

Formula for test statistic would be

$\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\=\dfrac{0.33-0.36}{\sqrt{\dfrac{0.36(1-0.36)}{240}}}\\\\=-0.96$

p value = 0.1685

Hence, p value is 0.1685.
