QUESTION 42 "An independent samples study exhibted the following sample characteristics: Sample 1, n = 32 with a sum of squared deviations (SS1) = 259.2. Sample 2, n = 35 with a sum of squared deviations (SS2) = 256.8. Calculate the estimated standard error of differences between means for these samples. (Be sure to round to the second decimal place)"

Transcribed Image Text:QUESTION 41
"A nutritionist measured the possible reduction in the mean weight of a sample n = 11 participants before and 6-weeks after they begin a new diet. She observed a
test statistic of t = -1.79, when testing at the alpha level of 0.05. What would she decide and which would be the MOST appropriate conclusion?"
O Reject Null Hypothesis (HO): There is a significant difference in weight after dieting for 6-weeks.
O Reject Null Hypothesis (HO): Weight significantly decreased after dieting for 6-weeks.
O Retain Null Hypothesis (HO): There is insufficient evidence the diet had a significant effect on weight.
