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?

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

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

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
