The average McDonald's restaurant generates $3 million in sales each year with a standard deviation of 0.4. Russell wants to know if the average sales generated by McDonald's restaurants in Nebraska is different than the worldwide average. He surveys 26 restaurants in Nebraska and finds the following data (in millions of dollars):
3.3, 3.2, 3.5, 3.3, 3.3, 3.4, 2.8, 3.5, 3.4, 2.5, 2.5, 3.6, 2.9, 2.9, 2.9, 3.5, 3.4, 2.7, 2.2, 2.5, 3.5, 3.6, 3.5, 3.7, 3.6, 2.8
Perform a hypothesis test using a 10% level of significance.
Step 3: Find the pp-value of the point estimate.
P(P( )=P()=P( )=)=
pp-value==
Step 4: Make a Conclusion About the null hypothesis.
Since the p-value= ?< or=""> =α,
