Constructing a Confidence Interval for a Population Mean
You intend to estimate a population mean μμ with the following sample.
| 14 | 17 | 17 | 15 |
| 11 | 13 | 16 | 14 |
| 16 | 13 | 11 | 11 |
You believe the population is normally distributed. Find the 95%
confidence interval for the population mean. Enter your answer as
an open-interval (i.e., parentheses)
accurate to two decimal places.
95% C.I. =
The statistical software output for this problem is:

Hence,
95% CI will be:
(12.57, 15.43)

Assume that a sample is used to estimate a population mean μμ. Find the 99.5% confidence interval for a sample of size 59 with a mean of 62.5 and a standard deviation of 12.2. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). 99.5% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
Assume that a sample is used to estimate a population mean μμ. Find the 99.9% confidence interval for a sample of size 62 with a mean of 19.4 and a standard deviation of 12.3. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). 99.9% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
Assume that a sample is used to estimate a population mean μμ. Find the 98% confidence interval for a sample of size 40 with a mean of 72.3 and a standard deviation of 14.5. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). 98% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
You intend to estimate a population mean u with the following sample. 32.2 53.1 76.1 40.2 33.2 26.4 55.6 15.4 You believe the population is normally distributed. Find the 99% confidence interval. Enter your answer as an open- interval (i.e., parentheses) accurate to twp decimal places (because the sample data are reported accurate to one decimal place). 99% C.1. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
17) In a survey, 26 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $32 and standard deviation of $14. Construct a confidence interval at a 90% confidence level. Give your answers to one decimal place. Enter the confidence interval in the form: Sample Mean ± Margin of Error You intend to estimate a population mean μμ with the following sample. 13 17 13 14 11 16...
