The table below summarizes the number of surface flaws found on the paintwork of new cars following their inspection after primer paint was applied by a new method. Note: You are not given proportions/probabilities in this table, but frequencies. So you have an additional step to take before you can calculate the mean and variance.
No. of flaws 0 1 2 3 4 5 6
No. of cars 3 7 11 10 3 1 1
Part a) Find the mean number of flaws per car. Please give your answer to two decimal places. The mean number of flaws per car is:
b) Find the variance of the number of flaws per car. Please give your answer to two decimal places. The variance of the number of flaws per car is:

The number of surface flaws in a plastic roll used in interior of cars has a poisson distribution with a mean of 0.07 flaws per square foot of plastic roll. Assume a car interior contains 9 square feet of plastic roll. If 10 cars are sold to a rental company, what is the probability that at most one car has a surface flaw? If 10 cars are sold to the rental company, what is the expected number of cars with...

The number of flaws per square yard in a type of carpet material varies with mean...
The number of flaws per square yard in a type of carpet material varies with mean 1.4 flaws per square yard and standard deviation 1 flaws per square yard. This population distribution cannot be normal, because a count takes only whole-number values. An inspector studies 171 square yards of the material, records the number of flaws found in each square yard, and calculates x, the mean number of flaws per square yard inspected. Use the central limit theorem to find...

A consumer organization inspecting new cars found that many had appearance defects (dents, scratches, paint chips, etc.). While none had more than three of thesedefects, 8% had three, 17% had two, and 27% had one defect. Find the expected number of appearance defects in a new car and the standard deviation. Compute the expected value of the number of appearance defects. E(appearance defects)equals=.85 (Round to two decimal places as needed.) Compute the standard deviation of the number of appearance defects....
