Solutions

Expert Solution

Solution: Here we have the given information are

n=300. =0.05

X= number of customers that BIG BURGER has really good food.

p= Proportion of  customers that BIG BURGER has really good food.= x/n =195/300=0.65

Null hypothesis: H0: P=0.60, i.e. the proportion of  60% of the clientele surveyed respond that BIG BURGER has really good

food.

Alternative hypothesis : H1: P>0.60 ( Right -tail alternative)

Test Statistic, Under H0, the test statistic is:

Now

Z=1.768

Conclusion: Since the alternative hypothesis is one-sided (right-tailed), we shall apply right-tailed test for testing significance

of Z. The significant value of Z at 5% level of significance for right-tail test is 1.645. Since computed value of Z=1.768 is

greater than 1.645, it is significant and we may reject the null hypothesis at 5% level of significance () and accept

alternative hypothesis.

That means manager claim BIG BURGER has really good food is exceeding the national average in Cleveland.
