1. General Questions a. Explain the difference between a population parameter and a sample statistic. Give at least one example of each. svid voy blues nisigx3 Shotudinleib nisiqxa b. Explain the difference between a margin of error and a standard error. c. Compare and contrast the normal distribution and the t-distribution. How are they alike? How are they different? When would we use one over the other?2. My husband recently had cataract surgery for both eyes and before the surgery, we did a little research into the cost of surgery per eye. It turns out there is quite a bit of variability in cost around the US. For a random sample of 10 states, the average cost for cataract surgery was $5340 (per eye) with a standard deviation of $2687. We assume that the costs for cataract surgery are normally distributed. a. Estimate the mean cost for cataract surgery nationwide using 90% confidence. Interpret your confidence interval. listaxa b. What is the margin of error? c. Could you have answered part (a) if the distribution of costs were not normally distributed? Explain. d. Would the interval in part (a) be wider or narrower if we had sampled more states? Explain. 1019 bisbristle bus Yon19 to nigism s nsewsed sonsnelliberit nisiqx d
