Construct the confidence interval for the population mean u. c= 0.98, x 15.4, o = 5.0, and n= 90 A 98% confidence interval for u is ( ). (Round to one decimal place as needed.)

B. The test​ statistic, t, =____   C. The​ P-value is ____ D. State the conclusion for the test. Reject H0. or Fail to reject H0.   E. Construct a confidence interval suitable for testing the claim that students taking nonproctored tests get a higher mean score than those taking proctored tests. ___<μ1−μ2<___   F. Does the confidence interval support the conclusion of the​ test? (Yes/ No) because the confidence interval contains (zero/ only positive value/ only negative values).

A statistics class is estimating the mean height of all female students at their college. They collect a random sample of 42 female students and measure their heights. The mean of the sample is 65.3 inches and the sample standard deviation is 5.4 inches. Find the 90% confidence interval for the mean height of all female students in their school? Assume that the distribution of individual female heights at this school is approximately normal. 1. The t value is 1.3025 2. The standard error has a value of -- 3. The margin of error has a value of 4. Find the 90% confidence interval for the mean height of all female students in their school

Construct the indicated confidence interval for the population mean µ using the t-distribution. Assume the population is normally distributed. c = 0.95, x= 13.8, s=0.59, n= 19 ..... (Round to one decimal place as needed.)
