The following random sample was selected from a normal population: 9, 11, 8, 10, 14, 8. Construct a 95% confidence interval for the population mean μ.
Added by Albert C.
Step 1
To find the sample mean, add up all the sample values and divide by the number of samples. For the given sample (9, 11, 8, 10, 14, 8), the calculation is as follows: \[ \bar{x} = \frac{9 + 11 + 8 + 10 + 14 + 8}{6} = \frac{60}{6} = 10 \] Show more…

Choosing a Distribution use the standard normal distribution or the $t$ -distribution to construct a $95 \%$ confidence interval for the population mean. Justify your decision. If neither distribution can be used, explain why. Interpret the results. If convenient, use technology to construct the confidence interval. In a random sample of 50 people, the mean body mass index (BMI) was 27.7 and the standard deviation was $6.12 .$ (Adapted from Centers for Disease Control).
