Question

Use at 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 = x - X2. Test HoH = Ovs II. O using the paired difference sample results d = 12.35,4 = 12.4.nu = 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 statistic p-value - 1

Answer 1

Find the test statistic and p value.

solutions - Here given that - d= », da Mos Md=0 vs Hai Md to d = 120 35 , Sd = 1204, nd=25 We use the bairld "t" test - jul. t = and 12.35 Sal Tha 1214 /sas t = 4.9798 which is required test Statistic- Here our test statistic is positive Now we find the P[z> 4.9798] By Standard normal table - P[z>4.97987 000005 Now the required p-value is 2 PLZ) 4 • 9796 3 pualue į loooool This this į required two tailed pralue which ý less than o.ooote
