1. If the range of a data set is 620 units then a good guessat the standard deviation of the data set is: a320. b124. c155. d620. 2. if a sample of 49 observations produced a point estimatefor the mean equal to 32 and a standard error for that estimateequal to 3.7, then the standard deviation of the sample is colsestto: a.82.0 b.16.81 c.25.9 d640.0 3. If a researcher has strong evidence against the nullhypothesis in a hypothesis test, the p-value of the test could bewhich of the following values? a 0.38 b0.98 c0.492 d0.003 4 Which one of the following null hypotheses should beaddressed to test the proposition that the X variable in aregression situation does not affect the Y variable? a Ho : B1 =0 b Ho: B1 =1 c.Ho : B1 = B0 d.H0 :B1 = slopeparameter 5. When a pooled varianceestimator is used to estimate the variances of two populations,which of the following statements must be assumedtrue? a. The mean of the populationsare equal. b. The means of the samplesdrawn from the populations are equal. c. The variances of thepopulations are equal. d.
