Consider the following statements.(A) Let A be an event in a sample space 2. Then A cannot be independent of itself.(B) Let X1,..., X, be an iid sample with population mean u and population variance o?.Then the sample mean X is an unbissed estimator for u and sample variance S is anunbiased estimator for o?.(C) For a test at significance level a, the p-value is the probability that Ho is true. Therefore,when p-value

3. Yoonie is a personnel manager in a large corporation. Each month she must review 16 of the employees. From past experience, she has found that the reviews take her approximately four hours each to do with a population standard deviation of 1.2 hours. Let X be the random variable representing the time it takes her to complete one review. Assume X is normally distributed. Let X be the random variable representing the mean time to complete the 16 reviews. Assume that the 16 reviews represent a random set of reviews.Find the 95th percentile for the mean time to complete one month's reviews.
a) Turkey is the most tea-loving country in the world. In 2014, the annual per capita consumption of tea in Turkey, denoted X, was normally distributed with a mean of 6:96 lb and a standard deviation of 2:36 lb. b)You pick a random sample of 5 people from Turkey (assume all of them are tea drinkers) and compute their mean per capita tea consumption to be only 3:98 lb. (i) What is the probability that her random sample has an average of 3:98 lb or lower, when the population average is as given above? (ii)Recall that a large sample size makes it unlikely thatthe sample mean is too far away from the population mean. How big a samsle should you have to draw so that the standard deviation of your sample average is less than 10% of its mean (i.e., less than 0.696 lb)?

5. One roll of a 'fair' six-sided die has an expected value or mean of 3.5 with a variance of 2.92. Suppose you plan to roll a die 60 times and compute the mean value in an effort to determine whether it is a fair die. (Fair in this case means that each of the six sides has an equal probability of being the roll value.) a. Use a z value of 1.85 to compute an interval around a fair die's population mean that can be compared to the mean of the 60 rolls of the potentially fair or unfair die if the mean of the sample is 3.3. b. When a z value of 1.85 is used to compute a confidence interval around an unfair die's sample mean from 60 rolls, what is the confidence level for the interval?
