Question

1. Consider the following data that represents a random sample out of a very large population: 0.43, 4.89, 5.29, 5.16, 0.59, 7.50, 4.48, 6.22 (a) Create a QQ plot of the data. Do you think it is reasonable to assume that the population distribution is normal? Explain your answer. (b) Denote µ to be the population mean. Regardless of your answer to (a), use R to perform the bootstrap with 2000 resamplings to create a 90% CI for µ. Since answers will differ for this question, it is critical that you show your R code and output to get full credit. (c) Regardless of your answer to (a), assume the population distribution is normal and use that fact to create a 90% CI for µ. (d) Compare your answers to parts (b) and (c). Which one do you think is more correct, and why?

I specifically need (c) and (d) answered. I already have a and b. Thanks!
