Explanation / Answer

P-value for interaction between ActivityT and age = 0.212 which is greater than 0.05

So, we fail to reject H0 at 5% level of significance and we can conclude that there is no interaction present between ActivityT and age.

P-value for ActivityT effect = 0 < 0.05,

So, we reject H0 at 5% level of significance and we can conclude that there is significant AcitivityT effect present on TimeOnline.

P-value for Age effect = 0.01 < 0.05,

So, we reject H0 at 5% level of significance and we can conclude that there is significant Age effect present on TimeOnline.

ans -> C. TNOETS Average time spent online by age group differs across dating and shopping sites.
