The following details are available with regard to a test of hypothesis for the population mean: H0:μ  = 60, σ = 60 x̅ = 72, test statistic = 1.20 what is the sample size?

Use the following ANOVA table to answer the question. Source Regression Error Total DF MS SS 355.22 177.61 10.91 2 76.38 431.60 7 How many observations were in the data set used to create this model? (i.e. what is n?) 18 15 10 9.

Given a 95% C.I. = (34.14 mm, 36.02 mm) for a sample of Wooly Bear caterpillar lengths (preceding problem), address the following.   Based upon the above information, I am _____ % confident that the 95% C.I. contains the sample mean.

Samples of body temperatures were taken from both men and women. The information from the samples is summarized below. Use a 0.05 significance level to to test the claim that men and women have different mean body temperatures. Men: n₁ = 15; 1 = 98.38° F; s₁ = 0.45°F Women: n2=91; 2 = 98.17°F; $2 = 0.65° F a. On your Work Upload or Calculations page, write down your hypotheses. Label which hypothesis is the claim. b. The test statistic is c. The critical value is . (Round to 3 decimal places.) (Round to 3 decimal places.) d. The p-value is (Round to 3 decimal places.) e. On your Work Upload or Calculations page, show how you made your decision using either the traditional or p-value method. The correct decision is to 1: Reject the null hypothesis, or 2: Fail to reject the null hypothesis. box.) (Type 1 or 2 in the f. On your Work Upload or Calculations page, write your conclusion/results summary. (Use the standard language about evidence and support of claims.)
