Question: Is a mean(µ=100) The (o) is we use sx of estimated EDFN T test Say we had the following: Population: µ=100, s=15 Sample: N=100, x=105 and sample mean (x=105)? Is there a statistical difference between 100 and 105? *Z test or T test? Since o is unknown, t test is appropriate. population) for the T test) Hypothesis testing for comparison of two means. 1-x :Tobt value from the given data (evidence score) N/S Steps in T Test Step1: Determine the Null and Alternative Hypothesis =rl :0H Step 2: Two-tailed Step 3: Select significant level a Step 4: T test Step 5: Find the critical value and determine if Tobt falls in the "reject" or "fail to reject" region of the Null hypothesis. Step 6: Calculate the Test statistic =N = rl Step 7-9: State the conclusion based on the result of the step 5. hypothesis is rejected (include a scientific notation.)
