The number of accidents per week at a hazardous intersection is a random variable with population mean 6.3 and population standard deviation 5.85. The distribution of the number of accidents is very right skewed.

Suppose we let x be the sample average number of accidents per week at the intersection during 9 randomly chosen weeks. What is the exact (that is, not approximate) probability that x is less than 8?

A) 0.80834
B) 0.61432
C) 0.61063
D) 0.79564
E) The exact probability cannot be calculated because we do not know the distribution of x.
