A company claims that the mean weight per apple they ship is 120 grams with a standard deviation of 12 grams. Data generated from a sample of 49 apples randomly selected from a shipment indicated a mean weight of 122.5 grams per apple. Calculate and interpret a 95% confidence interval for the mean weight per apple. 4. Section 7.4; Problem 6: Which test should be used here? A. One sample z-test for means B. One sample t-test for means 5. Section 7.4; Problem 6: Confidence Interval A. [119.68, 125.32] B. [119.05, 125.95] C. [119.62, 125.38] D. (113.61, 131.39] E. [119.14, 125.86] 6. Section 7.4; Problem 6: Interpretation A. 95% of the population falls within the interval specified. B. 95% of the sample was used to calculate the mean. C. We are 95% certain that the sample mean falls within the interval. D. We are 95% certain that the population mean falls within the interval. E. The sample mean will exactly equal the population mean 95% of times
