Question

a researcher wants to determine the number of televisions in a household.he conducts a survey of 40 random select house and I obtains data in accompying tabe. what is the relative frequency distribution of the data

Answer 1

The relative frequency (RF) can be calculated as follows:

`RF=\frac{F}{\sum ^{}_{}F}`

where RF is the relative frequency, F is the value of the frequency, and ∑F represents the sum of all frequencies.

Using a spreadsheet, we can get the following table:

Based on this table, we can see that ∑F = 40. Thus, we have to divide each frequency by 40 to get the relative frequency. As an example, using the first, second, and third row:

`RF_1=(1)/(40)=0.025`
`RF_2=(15)/(40)=0.375`
`RF_3=(13)/(40)=0.325`
