Question

Write the mathematically and identify H_0 and H_a. Find the critical value(s) and identify the rejection(s). Find the standardized test statistic. Decide whether to reject or fail to reject the null hypothesis An environmental agency recently claimed more than 26% of consumers have sotpped buying a certain product because of environmental concerns. In a random sample of 1100 consumers, you find 32% have stopped buying the product. At alpha = 0.03, do you have enough evidence to support the claim?

Explanation / Answer

A) the null hypothsis = Ho= p= 0.26

the alternat hypothesis = Ha= p>0.26

therefore option A is correct

b) as the alpha = 0.03

the sidtribution is normal as n is high

therefore from the z table the critical region = z>1.771

c)as this is a right tail test therefore the graph in option B is correct
