Jlenok [28]

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

$Z = \frac{x-mean}{S.D}$

$Z = \frac{55-70}{55}$

Z = -0.27

<u><em>Final answer</em></u>:-

<em>Todd's Z-score is - 0.27 </em>
