A group of 50 participants was divided equally into 5 groups. A Tukey HSD produced a value that led to the conclusion that Mean 1 was significantly larger than Mean 2, p 05. Which of the following situations would lead to such a conclusion? X1-13, X2-5, MSerror-36; T, = 54, 12-36. MSerror-240: , 5,T, = 2, MSerror 40: none of the other alternatives are correct.

Explanation / Answer

here for 0.05 level and 4,14 degree of freedom critical value =3.112

as test statistic is not greater then critical value ; we can not reject null hypotheiss

for not reejcting null hypothesis may lead to type II error

hence optionA (type II)

3) for this part is same as part 2 ; please reply
