“22.8, 24.8, 24.8, 26.0, 26.0, 26.2,”“27.0, 27.2, 27.4, 27.4, 27.4, 27.6,”“27.9, 27.9, 28.2, 29.4, 29.6, 29.8,”“30.4, 31.1, 31.4, 32.4, 33.1, 33.2,”“33.4, 33.9, 35.3, 35.7, 36.3, 40.2”
“n=30, number of classes=sqrt{n}”
a) We can use 6 classes.
b) Develop a frequency distribution table for the data in Table 1. Take 22.8 as the lower limit of the first class.
“begin{matrix}n 22.8text{—}25.7 & 3 \n 25.8text{—}28.7 & 12nend{matrix}”“begin{matrix}n 28.8text{—}31.7 & 6 \n 31.8text{—}34.7 & 5nend{matrix}”“begin{matrix}n 34.8text{—}37.7 & 3 \n 37.8text{—}40.7 & 1nend{matrix}”
