You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 48 business days, the mean closing price of a certain stock was $111.82. Assume the population standard deviation is $11.45. Question content area bottom Part 1 The 90% confidence interval is ( enter your response here, enter your response here). (Round to two decimal places as needed.) Part 2 The 95% confidence interval is ( enter your response here, enter your response here). (Round to two decimal places as needed.) Part 3 Which interval is wider? Choose the correct answer below. The 90% confidence interval The 95% confidence interval Part 4 Interpret the results. A. You can be 90% confident that the population mean price of the stock is between the bounds of the 90% confidence interval, and 95% confident for the 95% interval. B. You can be 90% confident that the population mean price of the stock is outside the bounds of the 90% confidence interval, and 95% confident for the 95% interval. C. You can be certain that the closing price of the stock was within the 90% confidence interval for approximately 43 of the 48 days, and was within the 95% confidence interval for approximately 46 of the 48 days. D. You can be certain that the population mean price of the stock is ei
