Answer:
We accept the alternate hypothesis and conclude that mean SAT score for Stevens High graduates is not the same as the national average.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 510
Sample mean, = 502
Sample size, n = 60
Sample standard deviation, s = 30
Alpha, α = 0.05
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 conclude that mean SAT score for Stevens High graduates is not the same as the national average.
<h2>8 unit tiles should be added</h2>
Step-by-step explanation:
Function given is . We wish to add more unit tiles to the function so that it becomes a complete square.
Since the given function is of order 2, the side of the square will be order 1. Let us assume a general order 1 expression to be the side of the square.
As the function forms the square after adding some unit tiles,
From comparision,
∴ 8 more unit tiles are required to complete the square.
