Answer:

2.82.

Explanation:

Let’s calculate the z-score using the formula:

z=σX−μ​

Substituting the given values into the formula, we get:

z=0.552.82−2.1​

This simplifies to:

z=0.550.72​

Now, you can calculate the final value using a calculator. The result will be the z-score for a GPA of 2.82.

Answer:

D) 1.309

Explanation:

we shall use the formula for Z-score, which is:


z = (x - \mu)/( \sigma)

where x is the given value, μ is the mean, and σ is the standard deviation. we use this to "standardize" the given value to the normal distribution with mean 0 and standard deviation of 1, from which we can use z-scores.

so, plugging in values we have:


z = (2.82 - 2.1)/(0.55) = 1.309
