N = 1 Mean = 31.48701 Std. dev. = 23.88382 Null hypothesis - mean = 25.2255 Degrees of freedom = 1038 Calculate: 1) Std. error 2) Confidence interval for 95% 3) Confidence interval for 99% 4) t

Step 1
error = Std. dev. / sqrt(N) = 23.88382 / sqrt(1) = 23.88382 Show more…

A sample of size n = 45 has sample mean x = 56.9 and sample standard deviation s = 9.4. Construct a 99% confidence interval for the population mean μ. Round the answers to one decimal place. A 99% confidence interval for the population mean μ is <μ< .

Given the sample data below: Sample A Sample B n = 18 n = 23 x̄ = 33.4 x̄ = 38.3 s = 5.3 s = 4.7 Assuming that μ1 is the population mean from which Sample A is drawn, then the 99% confidence interval for the difference of the means μ1 and μ2 would be < μ1 - μ2 < Note: Use 1-decimal place accuracy and use the degree of freedom formula as discussed in the lecture.

If using the 95% confidence interval from this output to determine whether you should retain or reject the null hypothesis, what is the value that you are looking for inside/outside of the 95% Confidence Interval? Sample Mean Mean Difference (The observed difference between Sample Mean and Pseudo Mu) Expected Mean Difference (The expected difference between Sample Mean and Pseudo Mu) Pseudo Mu
