Question

According to a published study, 13% of men has been involved in a minor traffic accident. Suppose we have randomly and independently sampled 400 and asked each whether he has been involved in a minor traffic accident. How many of the sampled men do we expect to have been involved in a minor traffic accident?

Answer 1

Answer: There are 52 men we can expect to have been involved in a minor traffic accident.

Step-by-step explanation:

Since we have given that

Percentage of men has been involved in a minor traffic accident = 13%

Number of men surveyed = 400

So, Number of sample men we can expect to have been involved in a minor traffic accident is given by

$\dfrac{13}{100}\times 400\\\\=0.13\times 400\\\\=52$

Hence, there are 52 men we can expect to have been involved in a minor traffic accident.
