Answer:
Strength and direction of the relationship.
Step-by-step explanation:
Given that A study finds a correlation coefficient of r = .32. This number gives you information about which of the following?
Group of answer choices Type of relationship and importance Statistical validity and external validity Statistical significance and effect size Strength and direction of the relationship.
We know that correlation coefficient represented by r is a measure of association between two variables. r can lie between -1 and 1. While negative correlation suggests inverse relationship positive a positive association.
0 correlation means the two variables are independent.
If nearer to 0, it represents weak correlation and nearer to 1 than 0 represents strong correlation.
Here r =0.32 a weak positive correlation
r represents
Strength and direction of the relationship.

Answer:
The area of the rectangle is 12 cm² (to two significant figures)
Step-by-step explanation:
To determine the area of a rectangle that is 2.1-cm wide by 5.6-cm long,
The area of a rectangle is given by
Area = l × w
where l is the length
and w is the width
From the question,
l = 5.6 cm
and w = 2.1 cm
Hence, Area of the given rectangle will be
Area = 5.6 cm × 2.1 cm
Area = 11.76 cm²
Now, we will convert the answer to two significant figures
Then,
Area = 12 cm²
Hence, the area of the rectangle is 12 cm² (to two significant figures)
Each angle is 90 degrees because 90 times 3 is 270.
