A local​ eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has
Mamont248 [21]

Answer:

Step-by-step explanation:

The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. This is the null hypothesis. It is written as

H0 : µ ≤ 34

The alternative hypothesis would be

Ha : µ > 34

This is a right tailed test because of the greater then symbol in the alternative hypothesis. Since the p value for the test was found to be 0.0281281, if we use a significant level of 0.05, then the conclusion would be

Reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average time spent on the deliveries does exceed 34 minutes.

Lily said that n=3 is a solution of the equation 16+n=18.Is Lily correct ?Explain
MAVERICK [17]
No, Lily is not correct. This is because 16+3 does not equal 18. So to find N, you take 18 and subtract 16. 
18-16=n 
18-16=2
so n=2
16+2=18.
