2. Use MINITAB to generate 10,000 observations from a binomial distribution with n = 50 trials and probability of success p = 0.02 . Create a histogram of the 10,000 observations. Comment on the shape of the distribution. Why does it makes sense for the histogram to have this shape?

3. Use MINITAB to generate 10,000 observations from a binomial distribution with n = 1000 trials and probability of success p = 0.02. Create a histogram of the 10,000 observations. Compare the shape of this distribution to the one you observed in the previous question. Explain the discrepancy between the two shapes.

Solutions

Expert Solution

Compare the shape of this distribution to the one you observed in the previous question. Explain the discrepancy between the two shapes.

from 2 and 3 shapes of the histogram both are different ,

graph 2 as positively skewed and graph 3 as symmetric .

it is approximation of the normal distribution of binomial distribution as sample size or trial increases then by approximation of normal distribution it becomes normal distribution .
