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

determined that home delivery will be successful if the average time spent on the deliveries does not exceed 3434 minutes. The owner has randomly selected 1818 customers and has delivered pizzas to their homes in order to test if the mean delivery time actually exceeds 3434 minutes. Suppose the​ P-value for the test was found to be 0.0281281. State the correct conclusion.

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.

Debora [2.8K]

Now

Cost Price (CP)

=  \frac{sp \:  \times 100}{100 + p\%}  \\  =  \frac{725 \times 100}{100 + 15}   \\  =  \frac{72500}{115}  \\  = rs \: 630.42

A volcanic cone has a diameter of 300 meters and height of 150 meters. What is the volume of the cone?
marusya05 [52]
So a diameter is twice the radius
The formula is:
V = π(r^2)(h/3)
the half of 300 is 150, so the radius is 150
V = π(150^2)(150/3)
V = π(22500)(50)
V is about <span>3534291.74</span>
