Consider the model, Yi = Bo + B1 X1,1 + B2 X2,1 + Uj, where sorting the residuals based on the X1, and X2,i gives: X1 X2 SSE-F 13.7 67.2 SSE-L 85.2 52.0 Compute the Goldfeld-Quandt statistic and decide if there is heteroskedasticity present for either regressor at the 5% critical-F value of 1.313 A. Not enough information. B. Reject the null for X1, and fail to reject for X2. C. Reject the null for X1, and reject the null...
1.You are performing a left-tailed z-test If α=.005α=.005, and your test statistic is z=−2.59, do you: Reject Null Hypothesis Fail to Reject Null Hypothesis You are performing a left-tailed z-test If α=.10, and your test statistic isz=-2.01, do you: Reject Null Hypothesis Fail to Reject Null Hypothesis You are performing a right-tailed t-test with a sample size of 15 If α=.01, and your test statistic is t=3.02t=3.02, do you: Reject Null Hypothesis Fail to Reject Null Hypothesis You are performing...
If the p = .08 and the α = .05, what decision would you make regarding the null hypothesis? Select one: a. To retain the null hypothesis b. To reject the null hypothesis c. There is not enough information to answer this question

Consider two models for the variable Yt: MA: Yt = Bo + B1 Yt-1 + Ut MB: Yt = A + A1 Yt-1 + A2 Xt + Vt While examining the prediction errors you obtain a Diebold-Mariano statistic of 1.78, what is your decision at the 10% significance level? A. Reject the null B. Fail to reject the null O C. Not enough information
You conduct a hypothesis test for the population mean. After you calculate the t test statistic, you find that your p-value = 0.04. Using alpha (a) = 0.01 level of significance, what is your decision regarding the null hypothesis? (either reject Ho and accept Ha, or fail to reject Ho)
You are performing a two-tailed z-test If a = 0.1, and your test statistic is z = - 3.4, do you: Reject Null Hypothesis O Fail to Reject Null Hypothesis
5. Mongolian gerbils are thought to be equally likely to be brown, white, or black in color. A random sample showed the following frequencies: White Black Brown 40 59 42 count (a) State the mull hypothesis (b) State the alternative hypothesis. (c) Calculate the test-statistic. (d) Estimate the p-value. (e) Using a 0.1, do we reject or fail to reject the null? (f) State your conclusion in terms of the problem (g) What category differed the most from what we...
