Question: An experiment is run that is claimed to have a binomial distribution with p = 0.15 and n = 18 and the number of successes is recorded. The experiment is conducted 200 times with the following results:
Number of Seccesses 0 1 2 3 4 5
Obeserved frequency 80 75 39 6 0 0
Using a significance level of 0.01, is there sufficient evidence to conclude that the distribution is binomially distributed with p = 0.15 and n = 18?

A new machine has just been installed to cut and rough-shape large slugs. The slugs are then transferred to a precision grinder. One of the critical measurements is the outside diameter.
An independent-measures research study was used to compare two treatment conditions with n = 4 participants in each treatment. The first treatment had a mean of M = 58 with a variance of s^2 = 28, and the second treatment had M = 52 with s^2 = 36.
In exercise identify (a) sample and (b) population. Also, find whether sample is likely to be representative of population.
Find the mean and the standard deviation of the age and hence determine and interpret the following:- The probability that the age isat least 45 years.
