<span>The total cost for Glenn Andrews is the value of the motorbike plus the sales tax. The sales tax is found multiplying the value times the percent sales tax rate, divided by 100. This is, tax sales = $3950 * 6% = $ 3950 * 6 /100 = 237. And the total cost was $ 3950 + $237 = $4187.</span>
So if you want it to be 9 less than your number (x) then you would subtract nine.
So it would be:
x - 9.
So if your "number" is 12 then you would substitute x for 12 and it would be 12-9. The answer is 3. So 3 is 9 less than a number (12).

Answer:
The hypothesis test is right-tailed
Step-by-step explanation:
To identify a one tailed test, the claim in the case study tests for the either of the two options of greater or less than the mean value in the null hypothesis.
While for a two tailed test, the claim always test for both options: greater and less than the mean value.
Thus given this: H0:X=10.2, Ha:X>10.2, there is only the option of > in the alternative claim thus it is a one tailed hypothesis test and right tailed.
A test with the greater than option is right tailed while that with the less than option is left tailed.
