Answer: We should reject the null if the test statistic is greater than <u>1.895</u>.
Step-by-step explanation:
We assume the population to be normally distributed.
Given: Sample size : 
, which is asmall sample (n<30), so we use t-test.
We always reject the null hypothesis if the absolute t-value is greater than critical value.
Therefore, We should reject the null if the test statistic is greater than <u>1.895</u>.

Answer:
x = -5
y = -2
Step-by-step explanation:
<em><u>Since you have y, plug that into the equation:</u></em>
-2x - 7y = 24
-2x - 7(-2) = 24
-2x + 14 = 24
<u><em>Then, subtract 14 from both sides:</em></u>
-2x + 14 = 24
- 14 - 14
__________
-2x = 10
<u><em>Finally, divide both sides by -2:</em></u>
-2x = 10
x = -5
So now you have, x = -5 and y = -2.
