We can use SOH, CAH and TOA, but first we must find the length of a hypotenuse:
h = $\sqrt{(-3) ^{2}+2^{2} } = \sqrt{9+4}= \sqrt{13}$
sin (theta)= 2/√13
cos ( theta) = -3/√13
tan (theta) = -2/3
cot (theta ) = -3/2
sec (theta) = 1/cos(theta ) = -√13/3
csc(theta ) = 1/ sin (theta) = √13/2

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 sample size condition). 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 nearly normal condition). We don't know about outliers, but we'll have to assume Ted doesn't have any, because they aren't mentioned.
