- A statistics practitioner took a random sample of 52 observations from a population whose standard deviation is 27 and computed the sample mean to be 102. Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits. A. Estimate the population mean with 95% confidence. Confidence Interval = B. Estimate the population mean with 95% confidence, changing the population standard deviation to 60; Confidence Interval: = C. Estimate the population mean with 95% confidence, changing the population standard deviation to 11; Confidence Interval=Construct the confidence interval for the population mean μ. c=0.98, x=7.7, σ=0.3, and n= 47 A 98% confidence interval for μ is ?Construct the indicated confidence interval for the population mean using the t-distribution.

- Let μ denote some population mean of interest and suppose a 95% confidence interval for μ is calculated to be (0.63, 0.73) and a 99% confidence interval for μ is calculated to be (0.61,0.75). Also, suppose that we want to test H0: μ = 0.77 vs. Ha: μ ≠ 0.77 What can you say about the corresponding p-value? Choose from following letters. a. The corresponding p-value will be smaller than 0.05 but larger than 0.01. b. The corresponding p-value will be larger than 0.05. c. the corresponding p-value will be smaller than 0.01. d. I can’t say anything about the corresponding p-value until I run the testSuppose you take a random sample of n = 80 Douglas College students and ask each student their age. You find that the mean age of students in this sample is X = 22.0375 years and the sample standard deviation is s = 3.2014 years. Fill in the blanks (rounding to four decimal places): The 95% confidence interval for the mean age μ of all Douglas College students is from ______ years to ______ years.Construct the indicated confidence interval for the population mean u using the t-distribution.

The confidence interval for the population variance is (Round to two decimal places as needed.)A standardized math test of fifth grade students produces a mean ?μ = 100 with a ?σ = 18. A sample of n = 36 students participated in "boost" training for their math skills. The sample M = 104 with S = 24. Did this "boost" training significantly improve students' math performance? Use ?α = .01.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.
