Question 3.Negative Binomial DistributionSuppose that in a group of insurance policies (which are independent as regards occurrence ofclaims), 45% of the policies have incurred claims (p-0.45). An auditor is examining the policiesin the group one by one until 6 policies with claims are found (r-6).(a) Find the mean of X, E(X).(b) Find the variance of X, V(X), and the standard deviation, SD(X).(c) Find P(X=7).(d) Find P(X>11).

ats 2. In the mid-19th century, Sir Francis Galton demonstrated, through extensive data collection, that many human characteristics such as height and IQ are distributed throughout the entire population in accordance with the normal distribution. Galton recorded the heights of 8585 men in Great Britain. This forms a normal distribution with a mean of 67 inches and standard deviation of 2.5 inches. (a) Graph this normal distribution and label the x-axis. (b) What proportion of these men were between 66 and 68 inches tall? belool vin (c) What fraction of the adult male population in Great Britain was within one standard deviation of the mean height? [Use the normal distribution function in Excel, not the Empirical Rule] (d) What height corresponds to the 95th percentile in the Galton study?
