32,000 clients; and S% of their clients submitted a claim in an auto insurance company's past year. We will take a sample of 200 clients and determine how many of them have submitted a claim in the past year. What is the sampling distribution of N(3200,0.2)? p~N(60, 152)? p~N(0.05, 0.003852)? Cannot be determined. Assume that the blood donors are independent. Questions 29-30: Suppose 20 donors come to a blood drive. The probability that the donor is not related in any way so that we can consider them independent donors. Let X be the number of donors who have type-0 blood, which is 0.06, a constant from donors that have type-0 blood. What is the sampling distribution of the sample proportion? For a sample of 100 donors, what is the Binomial ([100, 0.06]) ~ Normal (0.06, 0.0237)? p ~ Normal(6.2, 0.37)? Cannot be determined. What is the sampling distribution of the sample proportion? For a sample of 300 donors, what is p ~ Binomial (200, 0.06)? p ~ Normal (12, 3.359)? p ~ Normal(0.06, 0.013711)? Cannot be determined. For a sample of 300 donors, what is the probability that the sample proportion is greater than 0.10? 0.0019? 0.181? 0.819? 0.991?
The executives at Sandbachian, Inc., having recently solved their widget crisis, have another major problem with one of their products. Many cities are sending complaints that their manhole covers are defective and people are falling into the sewers. Sandbachian, Inc. is pretty sure that only % of their manhole covers are defective, but they would like to do a study to confirm this number. They are hoping to construct a 95% confidence interval to get within 0.01 of the true number.
