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 42 business days, the mean closing price of a certain stock was $119.21. Assume the population standard deviation is $10.33 The 90% confidence interval is () (Round to two decimal places as needed ) The 95% confidence interval is ( (Round to two decimal places as needed.) Which interval is wider? Choose the correct answer below. The 95% confidence interval The 90% confidence interval Interpret the results O 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 O B. You can be certain that the closing price of the stock was within the 90% confidence interval for approximately 38 of the 42 days, and was within the 95% confidence interval for approximately 40 of the 42 days O C. 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. O D. You can be certain that the population mean price of the stock is either between the lower bounds of the 90% and 95% confidence intervals or the upper bounds of the 90% and 95% confidence intervals
