Below is the graph of y = g(x)
1 answer:
Instead of y = g(x)^2, it should be y = g(x)+2
What this means that every point on g(x) will be shifted up 2 units. A point like (2,-1) which is the saddle point shown on the graph, will move up to (2,1) after you shift up 2 units. Every other point will follow the same path. Another example: The point (0,-5) -- which is the y intercept -- will move up to (0,-3).

Answer:
The test statistic for this test is 3.82.
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis,
is the standard deviation of the population and n is the size of the sample.
In this question:
So
The test statistic for this test is 3.82.
