Question

Research indicates that charitable giving is more common among older adults, though increased giving by Millennials is part of a growing trend. We examine charitable giving (measured in dollars) for two age groups: (1) 30–39 years and (2) 50–59 years of age, based on data from the GSS2014. Assume alpha = .05 for a two-tailed test. What can you conclude about the difference in giving between the two age groups? Total donation past year R and immediate family 30-39 n=62 mean=1145.32 Std dev=2611.793 std error mean=331.698 50-59 N=82 mean 1583.24 std dev=3661.561 std error mean 404.352 Equal variances assumed f=1.318 sig .253 t=-.800 df=142 sig 2 tailed=.425 equal variances not assumed t=-.837 df=141.568 sig 2 tailed=.404

Explanation / Answer

The Null and Alternative Hypothesis are

H0: The charitable giving is same in both the age groups.

Ha: There is diference in the giving between the two age groups.

The Test statistic t=-.800

The degrees of freedom are df=142

The P-value is (sig 2 tailed) p=.425.

Since p=0.425 < alpha=0.05, it is concluded that the null hypothesis is not rejected.

SO we conclude that , The charitable giving is same in both the age groups.
