H0: The Earth is not at the center of the Universe
Let’s say you’re an amateur astronomer and you’re convinced they have all got it wrong. You want to prove that the Earth IS at the center of the Universe. You set out to prove the alternate hypothesis and sit and watch the night sky for a few days, noticing that "hey, it looks like all that stuff in the sky is revolving around the Earth!" You therefore reject the null hypothesis and proudly announce that the alternate hypothesis is true — the Earth is, in fact, at the center of the Universe!

T or F

T or F

Answer 1

1. True.

The provided is an example of committing type 1 error.

Since type 1 error occurs when we reject the null hypothesis when it is true.

Given null hypothesis, the Earth is not at the center of the universe is true. Still we reject the null hypothesis therefore we commit type 1 error.

2.True.

The statement: people with an "A" type personality have a higher chance of dying from heart attack is a alternative hypothesis.

3.True

The provided is an example of a hypothesis pair.

Which is

H0: The Earth is not at the center of the universe.

Vs

H1: The Earth is at the center of the universe.

In alternative hypothesis we put the researcher's claim.

4.True

The statement: People with an "A" type personality have a higher chance of dying from a heart attack denotes one tail test.

That is upper tail test.
