sesenic [268]

Answer: b. 1.94

Step-by-step explanation:

For binomial distribution model , the formula to find standard deviation is given by :-

$\sigma=\sqrt{np(1-p)}$

Given : The portability that the offices she visits will eventually purchase her product: p=0.25

The number of offices she visited = 20

We assume that the binomial is an appropriate model for the number of offices that make a purchase.

Then, to find the distance of the possible number of sales Tina could observe from the overall mean number of sales we find standard deviation.

$\sigma=\sqrt{np(1-p)}\\\\=\sqrt{20(0.25)(0.75)}\\\\=\sqrt{3.75}=1.9364916731\approx1.94$

Hence, the correct answer is option (b).
