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
