Answer:
Step-by-step explanation:
Given that a large consumer goods company ran a television advertisement for one of its soap products.
B = individual purchased the product S = individual recalls seeing the advertisement B∩S = individual purchased the product and recalls seeing the advertisement
The probabilities assigned were P(B)=.20,P(S)=.40, and P(B∩S)=.12
a) P(B/S) =
Yes we can continue the advt since P(B/A) >P(B)
b)
It is preferable to continue advt as chances of purchase after seeing advt is more than purchase without seeing advt.
c) P(B/S) =
The II advt has the bigger effect since conditional prob is more here.
Answer:
you<u> accept </u>the alternative hypothesis
Step-by-step explanation:
The null and alternative hypothesis can be computed as follows:
The sample proportion
The test statistics can be computed as:
Z = -2.5
The P-value = 2( Z< -2.5)
From the tables;
The P-value = 2 (0.0062)
The P-value = 0.0124
The significance level = 0.01
Since the P-value is > significance level; we fail to reject the null hypothesis.
Conclusion: we accept the alternative hypothesis
