QNT 561 FINAL EXAM Q&A.Set 1  A market researcher is interested in determining the average income for families in San Mateo County, California. To accomplish this, she takes a random sample of 300 families from the county and uses the data gathered from them to estimate the average income for families of the entire county. This process is an example of o Inferential statistics  If x is a binomial random variable with n=10 and p=0.8, what is the probability that x is equal to 4? o ...
