"From the results below, is it true that 95% of the sample means will fall between 10.99408 and 11.00192 inches? Explain.
Problem is to estimate the mean paper length with 95% confidence Mean- 11 inches
Standard deviation of the length is 0.02inches Random sample 100 sheets
Mean paper length is 10.998 inches.
Z=1.96 for 95% Confidence.
Mean + or – stand dev/square root n = 10.998 + or – 0.02/square root (100)
     = 10.998 +or – 0.00392
     = 10.99408 ≤ µ ≤ 11.00192
