1 DU MA MSc Statistics Topic:- DU_J18_MA_STATS_Topic01 1) In analysis of variance problem involving 3 treatments with 10 observations each, SSE= Then the MSE is equal to: [Question ID = 2313] [Option ID = 9252] [Option ID = 9249] [Option ID = 9251] [Option ID = 9250] 14.8 [Option ID = 9252] 2) If the variability due to chance decreases, the value of F: [Question ID = 2309] 1. Decreases [Option ID = 9234] 2. Stay the same [Option ID = 9235] 3. Increases [Option ID = 9233] 4. Nothing can be said from given information [Option ID = 9236] Increases [Option ID = 9233] 3) If an unbiased coin is flipped till a first Head occurs, then the sample space is: [Question ID = 2284] 1. [Option ID = 9135] 2. [Option ID = 9136] 3. [Option ID = 9134] 4. [Option ID = 9133] [Option ID = 9136] 4) The listing of elements in population with distinct identifiable number is classified as: [Question ID = 2305] 1. Regularity experimental frame [Option ID = 9219] 2. Frame for experiment [Option ID = 9220] 3. Direct experimental frame [Option ID = 9217] 4. Indirect experimental frame [Option ID = 9218] Frame for experiment [Option ID = 9220] 5) When there is rough linearity between the principal variable Y and the auxiliary variable X, but there is no proportionality, the link between Y and X can be exploited to improve simple random sample estimator by using:
2 [Question ID = 2307] 1. Both Ratio estimator and Regression estimator [Option ID = 9227] 2. Combined estimator [Option ID = 9228] 3. Regression estimator [Option ID = 9226] 4. Ratio estimator [Option ID = 9225] Regression estimator [Option ID = 9226] 6) In LSD with 5 treatments and one missing plot, the error degrees of freedom is: [Question ID = 2310] [Option ID = 9238] [Option ID = 9239] [Option ID = 9240] [Option ID = 9237] 11 [Option ID = 9239] 7) In the context of characteristic function of a random variable, which one of the following statements is false? [Question ID = 2293] 1. It always exists. [Option ID = 9169] 2. It is uniformly continuous on R. [Option ID = 9170] 3. It is not independent of change of origin and scale. [Option ID = 9171] 4. If characteristic function of sum of two random variables is same as the product of their individual characteristic functions, then the variables are independent. [Option ID = 9172] If characteristic function of sum of two random variables is same as the product of their individual characteristic functions, then the variables are independent. [Option ID = 9172] 8) The area under a normal curve between one standard deviation on either side of the mean is: [Question ID = 2285] 1. 95% [Option ID = 9138] 2. 68% [Option ID = 9139] 3. 60% [Option ID = 9140] 4. 99% [Option ID = 9137] 68% [Option ID = 9139] 9) In case of two attributes A and B if (A) = 30, (B) = 40, N = 200, then for A and B to be negatively associated the frequency of the class AB will be: [Question ID = 2289] 1. 0 < (AB) < 6 [Option ID = 9155] 2. (AB) = 6 [Option ID = 9154] 3. (AB) = 0 [Option ID = 9153] 4. (AB) > 6 [Option ID = 9156] 0 < (AB) < 6 [Option ID = 9155]
3 10) Suppose that there is a chance for a newly constructed building to collapse, whether the design is faulty or not. The chance that the design is faulty is 10%. The chance that the building collapses is 95% if the design is faulty and otherwise it is 45%. If it is seen that the building has collapsed, then the probability that it is due to faulty design is: [Question ID = 2277] [Option ID = 9108] [Option ID = 9106] [Option ID = 9107] [Option ID = 9105] 0.19 [Option ID = 9106] 11) If ANOVA procedure is applied to the data obtained from 5 samples, where each sample contains 9 observations, then the degrees of freedom for critical value of F are: [Question ID = 2312] 1. 5 and 9 [Option ID = 9245] 2. 4and 44 [Option ID = 9247] 3. 4 and 40 [Option ID = 9248] 4. 4 and 8 [Option ID = 9246] 4 and 40 [Option ID = 9248] 12) The ages of 7 family members are 2, 5, 12, 18, 38, 40 and 60 years respectively. After 5 years a new member aged x years is added. If the mean age of the family now goes up by 1.5 years, then the value of x (in years) is: [Question ID = 2287] 1. 2 [Option ID = 9146] 2. 1 [Option ID = 9145] 3. 3 [Option ID = 9147] 4. 4 [Option ID = 9148] 2 [Option ID = 9146] 13) [Question ID = 2311] 1.
