The z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10
<h3>How to transform the scores?</h3>The sample scores are given as:
2, 3, 5, 5, 6.
Calculate the mean and the standard deviation using a statistical calculator.
From the statistical calculator, we have:
--- mean
--- standard deviation
The z-score is then calculated using
Where:
x = 2, 3, 5, 5, 6.
So, we have:
Hence, the z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10

Answer:
Step-by-step explanation:
The perimeter is the sum of the side lengths of the shape. Since a square has equal side lengths, each side must be the same. Divide 52/4=13cm. 13cm is the length of 1 side. Area is length times width, and since each side is 13, multiply 13cm*13cm to get the area, which is ,

Answer:
a) 910
b) 828100
c) 144320
Step-by-step explanation:
a. ∑y
This is the sum of all values of y. So
b. (∑y)^2
This is the square of the sum, so the square of 910, that we found in the previous item.
910² = 828100
c. ∑y^2
This is the sum of the squares of each amount spent. So
