Write the word or phrase that best completes each statement or answe s the question. 3) In a completely randomized design experiment, 10 experimental units were randonly 3) chosen for each of three treatment and a quantity was measured for each unit within each group. In the first steps of testing whether the means of the three groups are the same, the sum of squares for treatments was calculated to be 3,110 and the sum of squares for error was calculated to be 27,000. Complete the ANOVA table Source Treatments Error Total E CHOICE. Choose the one alternative that best completes the statement or answers A certain HMO is attempting to show the benefits of managed care to an insurance co IMO believes that certain types of doctors are more cost-effective than others. One rtification level is an important factor in measuring the cost-effectiveness of pt.ysi vestigate this, the HMO obtained independent random samples of 25 physicians f ee certification levels-Board certified (C); Uncertified, board eligible (E); and U igible ()-and recorded the total per-member, per-month charges for each (a sicians). In order to compare the mean charges for the three groups, the data analysis of variance. Write the null hypothesis tested by the ANOVA

Explanation / Answer

1)
df treatment = 4-1 =3
MST = SST/df
= 9000/3 = 3000
B) is correct

2)

using excel
=F.DIST.RT(2.52,3,14)
= 0.1

or same can be found using F distribution tables

C) is correct
