... 28. [$2,021, $2,617] This interval does contradict the claim of the college president since the candidate values for the average are all lower than the value he claimed. 29. [125.9, 131.9] No, the lowest number in the interval is higher than 122 lbs, so we do not have evidence that the children on a ...

Interpretation of Somers` D under four simple models
... where Φ−1 (·) is the inverse standard Normal cumulative distribution function. Figure 3 gives Somers’ D as a function of the mean difference, expressed in SD units. Again, we see a sigmoid curve, but this time Somers’ D is increasing with the alternative parameter. Note that a mean difference of 1 S ...

... Notice that X ~ Uniform(6); i.e. X has a uniform distribution on the integers from 1 to 6. Indeed, the probability of observing any one of these integer values (the value on the upper face of the rolled die) is the same for any value. Thus, X must be a uniform random variable. ...
