Answer:
Null Hypothesis, : = $9
Alternate Hypothesis, : > $9
Step-by-step explanation:
We are given that a report on a certain fast food restaurant states that μ, the mean order total, is $9. The manager of the restaurant believes the mean is higher.
A random sample of orders will be selected. The sample mean x¯ will be calculated and used in a hypothesis test to investigate the belief.
<u><em>Let </em></u><u><em> = the mean order total</em></u>
So, Null Hypothesis, : = $9
Alternate Hypothesis, : > $9
Here, <em><u>null hypothesis states that</u></em> the mean order total is equal to $9 and the manager claim's is not correct.
On the other hand, <em><u>alternate hypothesis states that</u></em> the mean order total is higher than $9 and the manager claim's is correct.
So, this would be the correct set of hypotheses for testing.
