(a) Is the relationship between Age and Earn statistically significant? Null > Ho: B = 0. , Alt - Ha: 13 #0 SEP 1 B = 5, 20 , SEB = 0 . 57 t= 51 2 29.123 year 0157 Null Rejected @ 5% level dif = not our lation coelfir thus it is statistifically = 1944-C.. AHAH: P/ C Significant - 1743 Using 95% confident CI = 1.96
