The weight of the circle that is double the weight of the triangle is 20 grams.
<h3>How to find weight ?</h3>
The weight of the rectangle is 80 grams.
The weight of the triangle is double the weight of the weight of the circle.
A rectangle is made up of 2 triangles. Therefore,
weight of each triangle = 80 / 2 = 40 grams
Since, the weight of the triangle is double the weight of the circle, the weight of the circle can be calculated as follows:
weight of circle = 40 / 2
Therefore,
weight of the circle = 20 grams.

Answer:
1. A matched-pairs t-test is valid, despite the sample being a small representation of the population, because the sample is a simple random sample and has a distribution with a single peak.
Step-by-step explanation:
The matched-pairs test is valid, for the reasons given in choice 1. Here's why:
- We do have matched pairs, not a 2-sample t-test, because each two are paired by the house they live in. Husband and wife live together: it's safe to pair them. (This rules out option 5.)
- Check conditions: The sample is large enough (fulfilling the <u>sample size condition)</u>. The sample data is fairly normal, although we don't know the population data, and the sample size is over 40, so we consider it a fairly large sample (fulfilling the <u>nearly normal condition)</u>. We don't know about outliers, but we'll have to assume Ted doesn't have any, because they aren't mentioned.
Add all the missing sides to make it a rectangle then divide by 2
