Your interview a random sample of 50 adults. The results of the survey show that 46% of the adults said they were more likely to buy a product when there are free samples At alpha = 0.01, can you reject the claim that at least 53% of the adults are more likely to buy a product when there a free samples? State the null and alternative hypotheses. Choose the correct answer below. A. H_0: p = 0.53 H_a: p notequalto 0.53 B. H_0: p lessthanorequalto 0.53 H_a: p > 0.53 C. H_0: p notequalto 0.53 H_a: p = 0.53 D. H_0: p greaterthanorequalto 0.53 H_a: pExplanation / Answer
The statistical software output for this problem is:
One sample proportion summary hypothesis test:
p : Proportion of successes
H0 : p = 0.53
HA : p < 0.53
Hypothesis test results:
Hence,
Hypotheses: Option D is correct.
Critical value = -2.33
z - test statistic = -0.99
Result: Option B is correct.
