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
So, to find the constant we do this:
1.2n = 93,000,000
so n = 77500000So, with this constant, we multiply n with 0.86
0.86n = <span>66650000
So Venus is about </span><span>66,650,000 million miles away from the sun</span>
Answer: 53
