Answer:

Step-by-step explanation:

It took 3 hours for her to deliver 189 total.

We need delivery per hour for our answer.

189 / 3 = 63

63 new papers are delivered per hour.

Which is a secant of circle A?

sergey [27]

Answer: line CD (fourth choice)

====================================================

Let's go through the choices one by one

1) Segment AB is a radius, which is not a secant line. We can rule this out.

2) line DE is a tangent line which only touches the circle at exactly one spot. We need something that cuts the circle in 2 spots for it to be a secant line. This can also be crossed off the list.

3) segment HG is a chord, which is fairly close to a secant line, but it must extend infinitely in both directions. In other words, it needs to be a line instead of a line segment. This is crossed off the list.

4) line CD is a secant line. It is a geometric line in that it goes on forever in both directions (it's not a segment, and not a ray either). Also, this line crosses the circle at 2 points, which contrasts it from a tangent line. This is the answer we want.

Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write wit

iren [92.7K]

Answer:

For the type I error, it's option D

For the type II error, it's option B

Step-by-step explanation:

A) A type I error is when we reject the null hypothesis even if it is true.

Let's set up the two hypotheses;

Null Hypothesis:

H0: p = 0.15

It represents: "The proportion of people who write with their left hand is equal to 0.15."

Alternative Hypothesis:

H1: p ≠ 0.15

In English: "The proportion of people who write with their left hand is different from 0.15" i.e not equal to 0.15

If we make a type I error, then it means we reject H0 (the null hypothesis) and go with the alternative hypothesis (H1). However, the reality is that H0 was the true hypothesis all along.

Thus, we reject the claim that the The proportion of people who write with their left hand is equal to 0.15 when in reality the proportion is actually 0.15

This means the answer for the first part is Option D

B) A type II error is when we fail to reject the null and must "accept" the null; however, the reality is that the alternative hypothesis was the true hypothesis. Hence, making a type two error means we reject the second hypothesis and make a mistake in doing so.

If we make a type II error, then we fail to reject the claim that proportion of people who write with their left hand is equal to 0.15, when the proportion is actually different from 0.15

Thus, he answer is Option B
