b.Use Minitab to generate 200 exponential random numbers with λ = 5. Again, create a QQ-plot (normal probability plot) of these numbers and comment on the fit

Expert Solution

a. Since p value is 0.945 which is very very large than 0.05 (taking alpha = 0.05), thus we will accept the null hypothesis and thus data strongly follows normal distribution.
