A researcher has developed a regression model from fifteen pairs of data points.He wants to test if the slope is significantly different from zero.He uses a two-tailed test and $\alpha$= 0.10.The critical table t value is _______.
A)1.771
B)1.350
C)1.761
D)2.145
E)2.068

Question

Quizplus · Accepted Answer

The critical table t value is 1.771. This is because the researcher is using a two-tailed test with a significance level of 0.10 and there are 15 pairs of data points. The degrees of freedom for the t-test is 14, which is found by subtracting 2 from the number of data points. The critical t-value for a two-tailed test with a significance level of 0.10 and 14 degrees of freedom is 1.771.
