Explain the difference between an interval estimator and a point estimator for mu. Choose the correct answer below. A. A single
inna [77]

Answer: D. A single number calculated from the sample that estimates a target population parameter is called a point estimator.

An interval estimator is a range of numbers that contain the target parameter with a high degree of confidence.

Step-by-step explanation:

When we evaluate an range of values for an unknown population parameter, then it is known as interval estimation .

A single number evaluated from the SAMPLE that estimates an unknown population parameter is known as a point estimator.

The general difference between point and interval estimator is the point estimator is a single value of target parameter while interval estimator is a range of numbers to estimate the values about the unknown population.

Use exterior angles to show that the angle sum of quadrilateral PQRS is 360°.​
Shkiper50 [21]

Answer:

I don't really know but one triangle is 180 degrees so two added together is 360 degrees...

but ohh I remembered

a=c+d (since a+b=180 and c+d+b=180)

e=g+h (since e+f=180 and g+h+f= 180)

and the fact is that c+d+g+h+b+f=the angle sum of quadrilateral PQRS

a+e+b+f= the angle sum of quadrilateral PQRS (by substitutions)

a+e+b+f=360 (four angles are from one origin so it's 360 degrees )
