Question
A research study was conducted to examine the differences between older and younger adults on perceived life satisfaction. A sample of ten older adults (over the age of 70) and ten younger adults (between 20 and 30) were give a life satisfaction test (known to have high reliability and validity). Scores on the measure range from 0 to 60 with high scores indicative of high life satisfaction; low scores indicative of low life satisfaction. The data are presented below. Compute the appropriate t-test. Older Adult Younger Adult 45 34 38 22 52 15 48 27 25 37 39 41 51 24 46 19 55 26 46 3626. What would be the null hypothesis in this study?*There is no significant relationship in the perceived life satisfaction between older and younger adult?There is a significant relationship in the perceived life satisfaction between older and younger adult?There is no significant difference in the perceived life satisfaction between older and younger adult?There is a significant difference in the perceived life satisfaction between older and younger adult?None of the above
Solution
The null hypothesis in this study would be: "There is no significant difference in the perceived life satisfaction between older and younger adults." This is because a null hypothesis in research typically suggests that there is no statistical significance between the set of observations. In this case, it would mean that the age of the adults (being older or younger) does not significantly affect their perceived life satisfaction.
