Answer:
Todd's Z-score is - 0.27
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<u><em>Step(i)</em></u>:-
Given data A test is normally distributed with a mean of 70 and a standard deviation of 10.
<em>Mean of the population 'μ' = 70 </em>
<em>Standard deviation of the Population ' σ ' = 10</em>
<em>let 'x' be the random variable in normally distributed</em>
<u><em>Step(ii)</em></u>:-
<em>Given raw score 'x' = 55</em>
Todd's Z-score
![Z = \frac{x-mean}{S.D}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7Bx-mean%7D%7BS.D%7D)
![Z = \frac{55-70}{55}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B55-70%7D%7B55%7D)
Z = -0.27
<u><em>Final answer</em></u>:-
<em>Todd's Z-score is - 0.27 </em>
Answer:

Answer:
True
Step-by-step explanation:
If you simplify an expression you divide for example:
4 x 6 - 10 would be dividing each number by 2, 2 x 3 - 5.
I'm not a genius so hopefully this is right and helps!
