5. The revenue (Y) for 1,000 food producing establishments in a country may bedescribed by an exponential distribution with parameter 2 = 1/(12*10°), useseed=1999.a. Generate the 1000 revenues and retain the integer portion.Obtain a histogram for the data in (a).b.c. Select a simple random sample of size 30 from this population (use seed2008).=d. Using this sample, estimate the average and total revenue and theassociated variance estimates.e. Construct 95% confidence intervals for the mean and total revenue of thepopulation.f. For this type of distribution, why is a simple random sampling not the bestdesign to yield a precise estimate? Suppose there was an auxiliaryinformation prior to the sampling design, propose an alternate samplingdesign that can lead to a more precise estimate. Explain how you could dothis.

QUESTION 9 The Department of Trade and Industry (DTI) conducted a survey to estimate the average number of employees per small and medium-sized enterprises (SME) in Free State. For a random sample of 144 SMEs in Free State, the DTI found that the average number of employees was 24.4. Assume that the population standard deviation is 10.8 employees and that the number of employees per SME is normally distributed. Using this information and rounding off the z or t values that you derive to 2 decimal places, the 95% confidence interval of the average number of employees per SME in Free State is for the lower limit andfor the upper limit. (Note: write your final answers to 3 decimal places and when writing your answer use "." (3.250) instead of "," (3,250) with no spaces between digits).
