What hypothesis states equality or no difference, or no relationship/effect?

• statistical hypothesis
• null hypothesis
• alternative hypothesis

Tags

CCSS.HSS.IC.B.3

What hypothesis states no equality or existence of differences, relationship, or effect?

• statistical hypothesis
• null hypothesis
• alternative hypothesis

CCSS.HSS.IC.B.3

Which hypothesis is generally formulated to look for evidence to support a claim called a research hypothesis?

• statistical hypothesis
• null hypothesis
• alternative hypothesis

CCSS.HSS.IC.B.3

In reality, the null hypothesis may or may not be true, and a decision is made to reject or not to reject it on the basis of the data obtained from a sample.

• True
• False

CCSS.HSS.IC.B.5

The level of significance is the maximum probability of committing a type II error.

• True
• False

Tags

CCSS.HSS.MD.A.2

A level of significance of 5% means:

• There's a 5% chance we're wrong
• There's a 5% chance we'll be wrong if we fail to reject the null hypothesis
• There's a 5% chance we'll be wrong if we reject the null hypothesis.
• There's a 5% chance you'll get an A on the test.
