Which summary statement best reflects the findings of the hypothesis test above. O The sample data suggests that happiness and technology use are dependent. The sample data suggests that the mean happiness scores of the the 3 technology groups are different. The sample data suggests that the mean happiness scores of the the 3 technology groups are not different. The sample data suggests that the proportion of happiness is the same for all technology groups.
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
