Based on past studies, you can assume that the standard deviation for the population for their maturity period is 15 days. You have been asked to determine a 95% two-sided confidence interval for the overall gestation period in the population. What would alpha be for this calculation (to 2 decimal places)? Answer: What value would you use for Z in this calculation (to 2 decimal places)? Answer: What would be the margin of error (E) for the confidence interval (to 2 decimal places)?

You have sampled 30 candy canes, and found that the sample mean for the amount of oil used was 5.5 grams, with a sample standard deviation of 1.5 grams. What would alpha be for this calculation (to 2 decimal places)? Answer: What would be the lower (smaller) chi-square distribution value to use in this calculation (to 2 decimal places)? Answer: What would be the upper (larger) chi-square distribution value to use in this calculation (to 2 decimal places)?
