[Solved] What is the 40 th percentile of a normal distribution with mean5 – Biostatistics (BIOL 350)

What is the smallest number of hepatomas that would have to be observed among the alcoholics with cirrhosis of the liver for the hepatoma experience in this group to differ from the hepatoma experience among alcoholics without cirrhosis of the liver?

Hint: Use a 5% probability of getting a result at least as extreme to denote differences between the hepatoma experiences of the two groups.

Note: If the Normal approximation to the Binomial distribution is valid, please use this approximation with the appropriate continuity correction applied to arrive at a solution to this problem
