Use the Student's t distribution to find tc for a 0.95 confidence level when the sample is 25. (Round your answer to three decimal places.)
Use the standard normal distribution or the t-distribution to construct a 90% confidence interval for the population mean. Justify your decision. If neither distribution can be used, explain why. Interpret the results. In a random sample of 40 people, the mean body mass index (BMI) was 26.6 and the standard deviation was 6.13.
Use the Student's t distribution to find tc for a 0.90 confidence level when the sample is 6. (Round your answer to three decimal places.)
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
Find the critical value tc for a 95% confidence level when the sample size is 18. Use Table 4 on page A10 (Appendix) A. 1.740 B. 2.110 C. 2.101 D. 1.734
Suppose that your sample size is 30 and that you wish to construct a 95% confidence interval. Your sample standard deviation is 40.9. Estimate your margin of error (MOE) using this information and the t-distribution table. Estimate your response to the first decimal point.
Use the Student's t distribution to find tc for a 0.90 confidence level when the sample is 25. (Round your answer to three decimal places.)
Use the Student's t distribution to find tc for a 0.95 confidence level when the sample is 3. (Round your answer to three decimal places.)
Use the Student's t distribution to find tc for a 0.95 confidence level when the sample is 29. (Round your answer to three decimal places.)
The number of unhealthy days based on the AQI (air quality index) for a random sample of metropolitan areas is shown. Construct an 80% confidence interval based on the data. Assume the variable is normally distributed. 23, 21, 14, 5, 40, 61, 39, 1, 0, 16
