An experiment has a single factor with fivefive groups and fourfour values in each group. in determining the among-group variation, there are 44 degrees of freedom. in determining the within-group variation, there are 1515 degrees of freedom. in determining the total variation, there are 1919 degrees of freedom. a. if ssaequals=8080 and sstequals=140140, what is ssw? b. what is msa? c. what is msw? d. what is the value of fstat?

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so, about which interval is it approximately symmetric?
