What will happen to the confidence interval if the sample size increases to 50?Get largerNothingGet smallerQuestion 13 (1 point) The percent defective for parts produced by a manufacturing process is targeted at 4%. The process is monitored daily by taking samples of sizes n = 160 units. Suppose that today's sample contains 14 defectives.How many units would have to be sampled to be 95% confident that you can estimate the fraction of defective parts within 2% (using the information from today's sample--that is using the result that p̂=0.0875)?Place your answer, as a whole number, in the blank. For example, 567 would be a legitimate entry.Question 15 (1 point) A sample of 9 production managers with over 15 years of experience has an average salary of $71,000 and a sample standard deviation of $18,000.Assuming that the salaries of production managers with over 15 years experience are normally distributed, you can be 95% confident that the mean salary for all production managers with at least 15 years of experience is between what two numbers.Place your LOWER limit, rounded to a whole number, in the first blank. Do not use a dollar sign, a comma, or any other stray mark. For example, 54321 would be a legitimate entry.___. Place your UPPER limit, rounded to a whole number, in the second blank.

For example, 65432 would be a legitimate entry.___Answer # 1 Answer # 2 Question 16 (1 point) After calculating the sample size needed to estimate a population proportion to within 0.05, you have been told that the maximum allowable error (E) must be reduced to just 0.025. If the original calculation led to a sample size of 1000, the sample size will now have to be___.Place your answer, as a whole number in the blank. For example, 2345 would be a legitimate entry.Question 18 (1 point) A random sample of college football players had an average height of 64.55 inches. Based on this sample, (63.2, 65.9) found to be a 92% confidence interval for the population mean height of college football players. Select the correct answer to interpret this interval.-We are 92% confident that the population mean height of college football players is between 63.2 and 65.9 inches.-We are 92% confident that the population mean height of college football palyers is 64.55 inches.-A 92% of college football players have height between 63.2 and 65.9 inches.-There is a 92% chance that the population mean height of college football players is between 63.2 and 65.9 inches.Question 20 (1 point) A random sample of college football players had an average height of 66.35 inches.
