The number of flaws per square yard in a type of carpet material varies with mean 1.5 flaws per square yard and standard deviation 1.3 flaws per square yard. An inspector studies 100 square yards of the material, records the number of flaws found in each square yard, and calculates the mean number of flaws per square yard inspected. what is the mean of the sampling distribution of the sample mean. What is standard deviation of the sampling distribution of the sample mean. use the central limit theorem to find the approximate probability that the mean number of flaws exceeds 1.8 per square yard.
