Our best estimate of the difference is 3. 8, but it could be anywhere between 2. 8 & 4. 8 since the interval doesn"t contain 0, the difference between 2 means is significant d = average difference. Sd = sdev. of mean difference df = nd 1. Note: same except zcrit is used when nd 30 & tcrit is used when nd < 30: confidence interval for 2 proportions. Degrees of freedom for fcrit dfnum = n1 1dfdenom = n2 1. Where the population with the greater variance in the alternative is women (n1: comparing 2 variances f-test (right-tailed, = 0. 05, dfnum = 41 1 = 40, dfdenom = 31 1 = 30. Measurement: assigning numbers to the object in such a way as to represent quantities of attributer associated with that object e. g. | weight: 180 lbs.
