A sample of 64 elements from a population with a standard deviation of 120 is selected....

A sample of 64 elements from a population with a standard deviation of 120 is selected. The sample mean is 170.

You are asked to construct a 95% confidence interval for μ.

The lower bound (or lower limit) for that interval is . . .

(NOTE: Round your final answer to 2 decimal places - such as 14.12 or 31.00 or 99.55)
