The average sales per customer at a home improvement store during the past year is $75 with a standard deviation of $12. The pro
borishaifa [10]

Answer:

0.0668

Step-by-step explanation:

Assuming the distribution is normally distributed with a mean of $75,

with a standard deviation of $12.

We can find the z-score of 78 using;

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }

\implies z=\frac{78-75}{\frac{12}{36} } =1.5

Using our normal distribution table, we obtain the area that corresponds to 0.25 to be 0.9332

This is the area corresponding to the probability that, the average is less or equal to 78.

Subtract from 1 to get the complement.

P(x>78)=1-0.9332=0.0668
