Question

rade.estion 21 View Policies Current Attempt in Progress Use a t-distribution and the given matched pair sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distribution of the differences is relatively normal. Assume that differences are computed using d = ' - 22. Test How = 0 vs H, H ousing the paired difference sample results d = 12.83, = 10.5,94 = 25. Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places. test statistici p-value = i Give the conclusion using a 5% significance level. Reject Ho. Do not reject Ho. Save for Later Attempts: 0 of 1 used Submit Answer

Answer 1

Test statistic,
t = (xbar - mu)/(s/sqrt(n))
t = (12.83 - 0)/(10.5/sqrt(25))
t = 6.11

P-value Approach
P-value = 0
As P-value < 0.05, reject the null hypothesis.
