Points will be deducted for homework turned in late and homework not turned in will receive a score of "zero". All work (computer and manual) should be shown for each problem so that partial credit may be given. ...

... The mode is useful primarily when there is a single, sharp maximum, in which case it estimates the central value. Occasionally, a distribution will be bimodal, with two relative maxima; then one may wish to know the two modes individually. Note that, in such cases, the mean and median are not very u ...

... Otherwise, entering the values of Po = 0.125, x = 46, and n = 234 into the 1-PropZTest in the calculator produces essentially the same test statistic and a P-value of 0.000465, when rounded. In either case, the null hypothesis is rejected at even the 1% level. 22. B – The correct set of ordered pair ...
