Q 1.

Are the means for the final exams the same for all statistics class delivery types? The table below shows the scores on nal exams from several randomly selected classes that used the different delivery types. Hybrid Face-to-Face 79 78 83 81 87 79 83 Assume that all distributions are normal, the three population standard deviations are approximately the same, and the data were collected independently and randomly. Use a level of significance of 0.05. El Part (a) State the null hypothesis. 0 Ho: At least two of the group means Mon/me, Mhybn-d, mace to face are not equal. 0 H0: \"online = \"hybrid = \"face to face- El Part(b) State the alternative hypothesis. 0 Ha: Hemline = \"hybrid = \"face to face- 0 Ha: At least two of the group means yon/me, \"hybrid: mace to face are not equal. El Part (c) Enter an exact number as an integer, fraction, or decimal. df(num) = Enter an exact number as an integer, fraction, or decimal. % 8 5L |H State the distribution to use for the test. 0 '5" a O I." o: N O O 11 TI 3 .61 w 25 O .2" 07 6'- What is the test statistic? (Round your answer to two decimal places.) |H What is the p-value? (Round your answer to four decimal places.) :] Part (h) Sketch a picture of this situation. Label and scale the horizontal axis, and shade the region(s) corresponding to the p-value. p-value p-value F F 1/2(p-value) 1/2(p-value) 1/2(p-value) 1/2(p-value) O F FIndicate the correct decision ("reject" or "do not reject" the null hypothesis) and write appropriate conclusions. (i) Alpha (Enter an exact number as an integer, fraction, or decimal.) (ii) Decision: 0 reject the null hypothesis 0 do not reject the null hypothesis (iii) Reason for decision: 0 Since a > pvalue, we do not reject the null hypothesis. 0 Since a > p-value, we reject the null hypothesis. 0 Since a pvalue, we do not reject the null hypothesis. 0 Since a > pvalue, we reject the null hypothesis. 0 Since a
