(round your answer up to the next multiple of 5.) b. organize the data into a frequency distribution using a lower limit of $70.

Sagot :

(a) Class interval of a given data is 36.

(b) Frequency distribution is 44.

We have given that,

total frequency = 44

lower limit = $70

number of class = 5

(a) we have to find class interval,

Class interval =  [tex]\frac{Max. number - min. number}{no. of classes}[/tex]

here maximum number is 264 and minimum number is 84

Class interval = [tex]\frac{264 - 84}{5}[/tex]

                      = [tex]\frac{180}{5}[/tex]

Class interval = 36

we have to round our value to the next multiple of 5

so the class interval will be 40.

(b) A frequency distribution is the pattern of frequencies of a variable. It is the number of times each possible value of a variable occurs in a dataset. There are three types of frequency distribution such as Cumulative frequency distribution, Relative frequency distribution, Relative cumulative frequency distribution.  

The frequency distribution is as follows:

Class interval           Frequency

 70 - 110                         6

 111 - 151                          5

152 - 192                       10

193 - 233                       14

234 -  274                       9

Total                              44

This is the organize data into a frequency distribution.
