 Yes sure, here I am uploading a pdf file having the CSIR UGC NET exam Question paper for Mathematics, there are objective types of the questions available. I have taken following questions from the attachment: 79. Consider a z5 factorial experiment laid out as a block design with 4 blocks of size 8 each. Suppose the principal block of this design consists of the treatment combinations (I), ab, de and five others. Which of the following interaction effects can be confounded In this design? 1. ABC, CDE, ABDE 2. ABC, CDE, ABCDE 3. AB, BC, AC 4. AB, CDE, ABCDE 80. For a bivariate data set (x,, y,), i = 1,2, ..., n, suppose the least squares regression lines are: Equation 1: Sx - 8y + 14 = 0 Equation 2: 2x - 5y + 11 = 0 Then which of the following statements are true? 1. The value of the correlation coefficient is -0.80 2. The value of the correlation coefficient is 0.80 3. The standard deviation of y is less than the standard deviation of x 1 " 1 " 4.(ji,7)=(2.3),where I = - ~ X , and jj=--Cy, n i=l n i=l    Remaining questions are in the attachment, please click on it……… Last edited by Aakashd; October 11th, 2019 at 05:19 PM.  |
