Answer:
Approximate probability that
is less than 2 = 0.1515
Step-by-step explanation:
Given -
Mean
= 2.2
Standard deviation
= 1.4
Sample size ( n ) = 52
Let
be the mean of accidents per week at the intersection during one year (52 weeks) .
probability that
is less than 2 =
=
Putting 
=
( Using Z table )
= 0.1515
Tan 44° = x/140
x = 140 tan 44°
x approx = 140 * 0.9657 = 135.198
Remember, we need to add another 4 feet, so the answer would be 139.198 feet
