Sample Parameters: n=50, df=50-1=49, Mean1=4, SD1=3 1-sample 2-tail ttest Assume Null Hypothesis Ho as Mean1 = 4 Thus, Alternate Hypothesis Ha as Mean1 ≠ 4
For Day 10, Mean2 = 4.6 from the data table. Find Probability P(X<t1)+P(X>t2) (Two-Tails Test values) so as to compare with Type-1 error α = 0.05
For Day 15, Mean2 = 3.8 from the data table. Find Probability P(X<t1)+P(X>t2) (Two-Tails Test values) so as to compare with Type-1 error α = 0.05
For Day 13, Mean2 = 4.0 from the data table. Find Probability P(X<t1)+P(X>t2) (Two-Tails Test values) so as to compare with Type-1 error α = 0.05
