Using the normal distribution, the area underneath the shaded region <u>between the two z-scores</u> is given by:
C. 0.6766.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
Hence, for this problem, the area is the <u>p-value of z = 0.75 subtracted by the p-value of z = -1.3</u>.
Looking at the z-table, the p-values are given as follows:
Then:
0.7734 - 0.0968 = 0.6766.
Which means that option C is correct.

<h2>Answer:</h2>
<u>1/2 is equal to 0.5, so </u><u>-1/2 is -0.5</u><u>.</u>
If you divide -1 by 2, you get -0.5.
That is Proof by Contradiction.
The famous one is the proof of the square root of 2 is irrational . First done by Euclid
Answer:
3x-4(4) =65
3x-16 =65
3x=65+16
3x=81
x = 27
