To find the 95% confidence interval for the true population mean.
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
