Answer:
![P(Z](https://tex.z-dn.net/?f=P%28Z%3C-2.5%29%20%3D0.0062097)
Step-by-step explanation:
From the question we are told that:
Test statistic t =-2.5
Generally the equation for Test for statistics is mathematically given by
![t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B%5C%3Dx-%5Cmu%7D%7B%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%20%7D%20%7D)
![t=-2.5](https://tex.z-dn.net/?f=t%3D-2.5)
Therefore
P-value from Z table is
For left tailed test
![P(Z](https://tex.z-dn.net/?f=P%28Z%3C-2.5%29%20%3D0.0062097)
therefore the P-value for the test is
![P(Z](https://tex.z-dn.net/?f=P%28Z%3C-2.5%29%20%3D0.0062097)
Less than means minus so 7 less than means -7
-2 times a number x means -2 times x or -2x
is greater than or equal to means <u>></u>
41=41
so
-7+-2x<u>></u>41
-2x-7<u>></u>41
add 7 to both sides
-2x<u>></u>48
divide both sides by -2
remember to flip sign since divided by negative
x<u><</u>-96
