Answer 1

Answer) Relative frequency is given by the frequency divided by the total sum of all the frequencies.

So, therefore,

the sum of all the frequencies = 392+421+293+80+369+798 = 2353

Relative frequency of more than once per month = 392/2353 = 0.166

Relative frequency of once every 1-3 months= 421/2353 = 0.178

Relative frequency of once every 4-6 months = 293/2353 = 0.124

Relative frequency of once 7-11 months = 80/2353 = 0.033

Relative frequency of once per year or less = 369/2353 = 0.156

Relative frequency of never = 798/2353 = 0.339
