Question:

One assumption for the two-sample t-test is that the “sampled populations are to be normally distributed.” What happens when they are not normally distributed? Repeat Exercise 10. 79 using two theoretical populations that are not normal and using samples of size 10. The exponential distribution uses a continuous random variable, it has a J-shaped distribution, and its mean and standard deviation are the same value. Use two exponential distributions with means of 50 and 80: Exp(50) and Exp(80). Check all three properties of the sampling distribution: normality, its mean value, and its standard error.
