Answer:
Correct option: "No, a probability of about 0.20 would be assigned using the relative frequency method if selection is equally likely."
Step-by-step explanation:
The assumption made is that all the 5 different packages are equally likely, i.e. the probability of selecting a package is [tex]\frac{1}{5}=0.20[/tex].
The probability distribution is shown below.
According to the probability distribution:
- The probability of a person preferring design 1 is,
[tex]P(X=1)=0.10[/tex]
- The probability of a person preferring design 2 is,
[tex]P(X=2)=0.05[/tex]
- The probability of a person preferring design 3 is,
[tex]P(X=3)=0.30[/tex]
- The probability of a person preferring design 4 is,
[tex]P(X=4)=0.40[/tex]
- The probability of a person preferring design 1 is,
[tex]P(X=5)=0.15[/tex]
So it can be seen that the probability of preferring any of the 5 designs are not same.
Thus, the designs are not equally likely.
The correct option is "No, a probability of about 0.20 would be assigned using the relative frequency method if selection is equally likely."
