Question

Use the following information from a multiple regression analysis to complete parts (a) through (c). n = 25 b_1 = 10 b_2 = 25 s_b_1 = 8 s_b_2 = 4 Find the test statistic. (Round to three decimal places as needed) Find the p-value. (Round to four decimal places as needed.) Is there evidence that the variable X_1 contributes to a model already containing X_2? NO, since the null hypothesis is Reject. NO, since the null hypothesis is not rejected. Yes, since the null hypothesis is not rejected. Yes, since the n hypothesis is Reject. Choose the correct hypotheses for X_2 below. H_0: beta_2 not equal to 1 H_1: beta = 1 H_0: beta_2 = 1 H_1: beta_2 not equal to 1

Explanation / Answer

Test statistic = 10/8 = 1.25

Degrees of freedom = n - 2 = 25 - 2 = 23

Hence,

p - value = 2*P(t > 1.25) = 2*0.11193 = 0.2239

No, since the null hypothesis is not rejected. Option B
