Question 9Suppose that prior to conducting a coin-flipping experiment, we suspect that the coin is fair. How many times would we have to flip the coin in order to obtain a 90% confidence interval of width of at most .18 for the probability of flipping a head?a)83b)84c)87d)50e)51f)None of the aboveQuestion 10It has been observed that some persons who suffer renal failure are diagnosed with it again within one year of the first episode. This is due, in part, to damage from the first episode. In order to examine the percentage of the persons who suffer renal failure a second time, a random sample of 1100 people who suffered renal failure was collected. It was observed that 17 of them again suffered renal failure within one year. Select a 90% confidence interval for the true proportion of those who suffer a second episode.a) [0.0114, 0.0516]b) [0.0144, 0.0716]c) [0.0124, 0.0416]d) [0.00936, 0.0216]e) [0.0104, 0.0616]f) None of the above
