I don’t see the statements. sorry:(
Answer: x - 2 + 5 = x - 12
Step-by-step explanation:
At first I was confused. Then I read the question again and translated it.
Less than translated means - 2.
A number, aka X.
and means plus(+).
when you put that together you get,
x - 2 + 5.
The next step is to translate to second part of the equation.
Is means equals(=).
So far we have: X - 2 + 5 = 12.
<em>This is where I got confused...</em>
After solving that peice, we have the words; " 12 less than the number it's self. I wasn't sure if 2 x's could be in the same equation. Now I know they can.
Above, we established that 'a number' is x.
Now, it's talking about that number again because it says; "The number itself." At first, I thought it was talking about 12 - 12! Then I realized that it's not.
The new equation, after understanding that in the second piece isn't 12 - 12, would be none other than,
x - 2 + 5 = 12 - x
I hope this helps!!

Answer:
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic is:
Therefore, the test-statistic is 
Now the F critical value at 0.02 significance level for df1 = 10- 1 =9 and df2 = 16 - 1 =15 is:
Since F statistic is greater than the F critical value, we therefore, reject the null hypothesis and conclude that there is sufficient evidence to support the claim that there is a difference in the variation in the listening times for men and women.
