Answer:
20 measured and 10 used
Step-by-step explanation:
Total number of participants is given as n = 10.
Number of treatment conditions = 2
Total measurements is therefore 2 × 10 = 20
Therefore, in total, 20 scores will be measured in the given study.
Now there are two samples and for each sample, for each sample we need to calculate the mean = Sum of value(measures)/Number of measures
mean = Sum of value(measures)/10
Therefore, we are going to have 20 measured and 10 used to calculate the sample mean and the sample variance.
The area formula for both a square and a rectangle is A = L*W, only in a square, the length and width are the same. It can be rewritten then as
where s is a side. If we have the length and width of the rectangle to be 32 and 2, respectively, then the area is 32*2=64. If the square is to have the same area, 64, we will fill it into our square formula for area like this:
. To solve for s we will take the square root of both sides to get s = 8 and s = -8. The 2 things in math that will never EVER be negative are time and distance/length so -8 is out. That means that the side lengths of the square is 8 meters.
