A Michigan study concerning preference for outdoor activities used a questionnaire with a six-point Likert-type response in which 1 designated "not important" and 6 designated "extremely important." A random sample of
n
₁
= 44 adults were asked about fishing as an outdoor activity. The mean response was x₁
= 4.9. Another random sample of
n
₂
= 49 adults were asked about camping as an outdoor activity. For this group, the mean response was x₂
= 4.1. From previous studies, it is known that ?₁
= 1.5 and ?₂
= 2.0. Does this indicate a difference (either way) regarding preference for camping versus preference for fishing as an outdoor activity? Use a 5% level of significance.


Note: A Likert scale usually has to do with approval of or agreement with a statement in a questionnaire. For example, respondents are asked to indicate whether they "strongly agree," "agree," "disagree," or "strongly disagree" with the statement.

O At the a = 0.05 level, we reject the null hypothesis and conclude the data are statistically significant. O At the a = 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant. O At the a = 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant. O At the a = 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. (e) Interpret your conclusion in the context of the application. O Fail to reject the null hypothesis, there is sufficient evidence that there is a difference between mean response regarding preference for camping or fishing. O Reject the null hypothesis, there is insufficient evidence that there is a difference between mean response regarding preference for camping or fishing. O Fail to reject the null hypothesis, there is insufficient evidence that there is a difference between mean response regarding preference for camping or fishing. O Reject the null hypothesis, there is sufficient evidence that there is a difference between mean response regarding preference for camping or fishing.
