Answer:
a.
Network CBS NBC FOX ABC
f 9 9 1 6
Relative f 0.36 0.36 0.04 0.24
Percent f 36 36 4 24
b.
CBS and NBC have done best in presenting top-rated television shows.
The most top rated shows are from CBS and NBC while ABC network also has top rated shows but CBS and NBC percentages are higher.
Step-by-step explanation:
a.
Network f Relative f Percent f
CBS 9 0.36 36
NBC 9 0.36 36
FOX 1 0.04 4
ABC 6 0.24 24
"f" represents the frequency of network.
"Relative f" represents relative frequency of Network.
"Percent f" represents percent frequency of Network.
Frequency is computed by counting the number of times value repeated in the data. So, the frequency distribution is
Network Frequency
CBS 9
NBC 9
FOX 1
ABC 6
Relative frequency is computed by dividing the frequency to the sum of frequencies.
sum of frequencies=9+9+1+6=25.
So, the relative frequency distribution is
Network Relative frequency
CBS 9/25=0.36
NBC 9/25=0.36
FOX 1/25=0.04
ABC 6/25=0.24
Percent frequency is computed by multiplying relative frequencies to 100.
So, the Percent frequency distribution is
Network Percent frequency
CBS 0.36*100=36
NBC 0.36*100=36
FOX 0.04*100=4
ABC 0.24*100=24
b.
From frequencies, relative frequencies and percent frequencies we can see the CBS and NBC have equally higher cont of top rated shows comparative to ABC and FOX. ABC has second highest top rated shows while Fox has least top rated shows among other networks.
