Question

​The following are the weights in kg. of 50 college students. Construct a frequency table, such that the width of each interval is 4 and the upper limit of the last class is 60. 42 ,45, 52, 42, 46, 54, 41, 37, 54, 44, 38, 45, 47, 50, 58, 49, 51, 42, 46, 37, 42, 39, 54, 39, 51, 58, 47 ,51, 43, 48, 49, 48, 49, 41, 41, 40, 58, 49, 49, 59, 57, 52, 56, 38, 46, 40, 51, 41, 51, 41, 20.

Answer 1

Dear Student,

$$\begin{gathered} \mathrm{Since}\mathrm{the}\mathrm{lowest}\mathrm{observation}\mathrm{is}20.\mathrm{Take}\mathrm{the}\mathrm{class}\mathrm{intervals}\mathrm{as} \\ 16-20,20-24,24-28,28-32,32-36,36-40,40-44,44-48,48-52 \\ 52-56,56-60 \\ \mathrm{The}\mathrm{frequency}\mathrm{distribution}\mathrm{table}\mathrm{is}\mathrm{shown}\mathrm{below}: \end{gathered}$$

Class Interval	Frequency
16-20	1
20-24	0
24-28	0
28-32	0
32-36	0
36-40	6
40-44	13
44-48	7
48-52	12
52-56	5
56-60	6
Total	50
