Suppose it is known that if you offer free samples o a product, at least 52% of adults are more likely to buy the product. You interview a random sample of 50 adults. The results of the survey show that 37% of the adults said they were more likely to buy a product when there are free samples. At a=0.01, can you reject the claim that at least 52% of the adults are more likely to buy a product when there are free samples?
Choose the correct answer below:
a) At the 1% significance level, there is enough evidence to reject the claim.
b) At the 1% significance level, there is not enough evidence to support the claim.
c) At the 1% significance level, their is enough evidence to support the claim.
d) At the 1% significance level, there is not enough evidence to reject the claim.
e) The test can not be completed
