First you need to understand the structure of the commission.
The first part is 6% commission on sales up to $500.
The second part is 8% commission on sales over $500.
Note that the second part doesn't mean that a sale of $800 gets 8% of $800.
It means that once we have reached $500, any *further* sales get 8%.
Since $800 is $300 more than $500, the commission is
6% of $500 +
8% of $300
The first thing she did was work out the excess above $500.
Then she worked out the two percentages in two separate parts.
The second part seems to have incurred a cut and past accident, not sure if that is yours or it was already done.
Answer:
Mean SAT score for Stevens High graduates are not the same as the national average.
Step-by-step explanation:
We are given the following information in question:
Population mean, μ = 510
Sample mean, = 501
Sample size, n = 50
Alpha, α = 0.10
Sample standard deviation, s = 30
First, we design the null and the alternate hypothesis
We use Two-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have,
Now,
Since,
We reject the null hypothesis and fail to accept it.
We accept the alternate hypothesis and mean SAT score for Stevens High graduates are not the same as the national average.
