Suppose $\displaystyle {n}={728},\overline{{x}}={33.8}$ and $\displaystyle \sigma={19.9}$.
Find the 98% confidence interval for a sample of size
Enter your answer by giving the lower and upper bounds, accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).

< $\displaystyle \mu$ <

Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
