nesearcher wanted to determine the number of televisions in households. He conducts a suney of 40 tandomly selected households and obeains the data in the accompanying table Complete parts (aj through 01 below Cick the icon to wew the table of teleeson counts (a) Are these data discrete or continuous? Explain A. The guen data are dscrete because they can only have whole nnter vales O B. The given data are continuous because they can take on any real value O C. The gven data are discrete because they can take on any real value D. The given data are continuous because they can only hae whole fumberaues (b) Construct a frequency distibution of the data Frequency (c) Construct a relative trequency distibution of the data cack to select your answerts)

Explanation / Answer

a. These data are discrete because they can only have whole number values.

Hence answer is A.

b. In statistics the frequency (or absolute frequency) of an event is the number of times the event occurred in an experiment or study.

c. To find the relative frequency, divide thefrequency by the total number of data values.

d. To find percentage of household with 3 television, check the relative frequency of x=3,

Which means P(x=3)=0.2

e. To find percentage of household with 4 or more television is relative frequency of x=4+x=5

So required percentage is 0.05+0.025= 0.075

Televisions Frequency 0 2 1 13 2 14 3 8 4 2 5 1
