Answer:
a^2 - 2a.
Step-by-step explanation:
Replace the y in g(y) by a - 1 and simplify.
g(a-1) = (a - 1)^2 - 1
= a^2 - 2a + 1 - 1
= a^2 - 2a.
Answer:
The value of the test statistic is
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(square roof of the variance) and n is the size of the sample.
In this problem, we have that:
So
The value of the test statistic is
In order to do that we would need to see the list of potential answers.
