In the question it is already given that 4 items are being purchased and their individual rates are also given. the percentage of tax that needs to be paid is also given. To find the total amount of tax that has to be paid, you can either calculate the taxes on individual items and then add them or you can add the total amount required for the 4 items and then calculate the tax. Both will yield the same result but the second process is easier.
Cost of all the 4 items purchased = (2.50 + 8.75 + 3.00 + 10.25)
= 24.50
Percentage of tax that needs to be paid = 6%
Amount of tax that needs to be paid = (6/100) * 24.50
= 147/100
= 1.47
So the amount of tax that needs to be paid is 1.47.
Answer:
d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.
Step-by-step explanation:
The type 1 error could be said to have been made if the null hypothesis is erroneously rejected.
In the scenario above :
The null hypothesis (H0) : mean = 40
Hence, if the Null hypothesis defined above is rejected when in fact the hypothesis that the mean miles per gallon is actually 40.
On the other hand, the type 2 error occurs when a null which is false is not rejected.
Hence, when a true null is rejected, a type 1 error is committed. Similarly, when a false null isn't rejected, then a type 2 error has been committed.
