A company that manufactures toothpaste is studying five different package designs. Assuming that one design is just as likely to
be selected by a consumer as any other design, what selection probability would you assign to each of the package designs? In an actual experiment, 100 consumers were asked to pick the design they preferred. The following data were obtained. Do the data appear to confirm the belief that one design is just as likely to be selected as another? Explain design number of times preferred. 1 5
2 15
3 30
4 40
5 10
The selection probability that would be assigned to each of the package designs , since they are equally likely is 1/5= 0.2
step-by-step explanation:
the data appear not to confirm the belief that one design is just as likely to be selected as another because 1 is preferred 5 times and 4 is preferred 40 times, this is very wide apart, and it confirmed the belief that one design is not as likely to be selected as another.
The key to finding the answers for these is to find a common denominator and multiply both the numerator and denominator by the number that helps to make a common denominator
