The results of an independent samples t-test are shown below. Are older people (those 30 or older) less sympathetic to the environmental movement than younger people (those younger than 30)? Or do younger people and older people not differ significantly in their feelings toward environmentalists? Using the SPSS results, test your hypothesis.

Note: Hi there! Thank you for posting the question. As your question has more than 3 parts, we have solved only the first three subparts for you. If you need any specific subpart to be answered, please re-submit the question by specifying the subpart number or name. (1). State the null and research hypothesis: The investigator is specifically interested to test whether younger people and older people not differ significantly in their feelings toward environmentalists. Denote µ1 as the population mean feelings toward environmentalists for younger people and µ2 as the population mean feelings toward environmentalists for older people. The test hypotheses are stated below: Null hypothesis: H0 : μ1 = μ2 That is, there is no significant difference in the mean feelings toward environmentalists for younger people and older people. Alternative hypothesis: H1 : μ1 ≠ μ2 That is, there is a significant difference in the mean feelings toward environmentalists for younger people and older people. The research hypothesis is Do younger people and older people not differ significantly in their feelings toward environmentalists.(2). Determine the level of significance: Level of significance: Level of significance is the probability of rejecting the null hypothesis H0, when the null hypothesis H0 is true. Since, the level of significance is not specified, the prior level of significance α = 5% = 5/100 = 0.05 can be used. Thus, the level of significance is α = 0.05. (3). Find the proper t test statistic: The P-value for the Levene’s test for equality of variance is 0.758. Since, the P-value of 0.758 is greater than the level of significance α = 0.05, there is enough evidence to conclude that the variances of two populations are equal. Therefore, the independent sample t test with the assumption of equal variances is appropriate in the given scenario. The t-test statistic is t = -0.132.
