Question

Juduus. QUESTION 2 Using the data below, construct a grouped frequency distribution (GFD). After constructing your GFD answer the questions given below by typing in the number of your answer. 52 40 The real class interval size for this GFD is The apparent class interval size for this GFD is The apparent lower limit of the first class interval of this GFD is class intervals. This GFD has a total of The real upper limit of the last class interval of this GFD is The largest frequency found for any of the class intervals in this GFD is

Answer 1

Date we have followings obsevation 81, 37, 49, 38,58, 48, 6? ,7.3, 33, 69, au, 40, 68, 58, F20, 37, 40, 61, 53,71 sample we make size = n220. Group pregunee dishibution, to frequency Ictasses 30-50 To 5o. Classes 30-35 . 35-40 Blo-45 us-so a Iso-SS Go to 70-25 2 Go 1651 65-70 2 . 3 Totay. 20

. The real internal size of GPD is 6 Because - - - Umir real interal size = Real appes - Real lower = 355 - 29.5 limit ② The apparent Lower limit class internal size this GFD is 5 for appesat lower linis intewall size 2 appenuht Upper limit = 35-30 . class internal of The appereent lower limit of first this GFD is 30 (fiest class is 30-35) @ The GFD has total of 9 class intervals. a class internal of The real upper limit of the last GPD is since class interich is is las class interval is. (70-75.) ③ The largest frequency found any of the class intenals in the this GFD is (30-40), (40-48) and 70-75 of The apperent upper limit of this GFD is 35 kiest since class elu internal fisst Class is (30-35)
