A type I error takes place if a given null hypothesis is rejected but is said to be true in the population such as the forecast shows it is snowing outside but actually it is isn't.
<h3>What is type 11 error?</h3>
A type II error is known to be a statistical term that tells the error that takes place when one fails not to accept a null hypothesis that is said to be really false. A type II error create a false negative.
- It known is known also as an error of omission. Example is the forecast shows that It is not snowing but it is actually snowing.
Note that:
- Type I error is false positive.
- Type II error is false negative.
The power of the test shows that:
- The Power is the likelihood of rejecting the null hypothesis even if it is false.
- Power is the likelihood of making the right decision that is to reject the null hypothesis even if the null hypothesis is false.
- Power is the likelihood of not making a Type II error and others.

Answer:
4.86 people/sq.miles
Step-by-step explanation:
the area of the state of Wyoming =
360 × 280 = 100,800 sq. miles
so, the population density =
490,408 ÷ 100,800
= 4.86 people/sq.miles
Answer:
Measurements were needed for multiple things, such as agriculture, construction, and trade. Also, many areas developed their own systems for measuring objects making it difficult as people from different places had different results. Eventually, the same system was adopted by the majority of people.
Step-by-step explanation:
The formula after making t subject of the formula is:
Step-by-step explanation:
Given formula is:
To make t the subject of the formula we have to isolate t
So,
<u>Cross-multiplying</u>
<u>Adding 4t on both sides</u>
<u>Subtracting 3q from both sides</u>
<u>Taking t common on left hand side</u>
<u>Dividing both sides by q+4</u>
The formula after making t subject of the formula is:
Answer:
74
Step-by-step explanation:
The cube root of 74^3 will be 74. The cub and cube root cancel each other out.
