Suppose a randomly selected sample of n = 68 men has a mean foot length of x = 26.7 cm, and the standard deviation of the sample is 3 cm. Calculate an approximate 95% confidence interval for the mean foot length of men. (Round the answers to one decimal place.)
____ to_____ cm


important note : When working on the confidence interval for the population mean, have the standard error go to 5 decimal places. Then, input the answers to the corresponding number of decimal places as stated in the instructions.

You may need to use the appropriate table in the Appendix of Tables to answer this question.
