Question

Given the null hypothesis: There is not significant linear association for ACT Math scores and 1s year college GPA. Do we reject or accept the hypothesis given the data below? Also T value is 1.973 and critical value is 0 .514.Data A: Students’ Abilities in Spatial Reasoning and Mathematical Ability

Data A: Students’ Abilities in Spatial Reasoning and Mathematical Ability

	ACT Math (X)	1st year college GPA (Y)
Mean	= 20.8	= 2.57
Standard Deviation	1.52	0.52
Correlation	r = .48
Sample size	n = 15

Answer 1

Here T value is 1.973 and critical value is 0.514

So T value is greater than critical value.

Hence, we reject null hypothesis.

So, There is sufficient evidence to conclude that there is significant linear association between ACT Math scores and first year college GPA.
