The probability of observing the experiment result, a sample mean, for example, or something more unusual just by chance if the null hypothesis is true is the definition of "P-Value."
<h3>What is null hypothesis?</h3>
A null hypothesis is a sort of statistical hypothesis which asserts that there is no statistical significance in a particular set of observations.
Using sample data, hypothesis testing is performed to determine the believability of a theory. It really is expressed as H0 and is also known to simply as "null."
Some key features regarding null hypothesis are-
- A null hypothesis is a statistical conjecture that claims there is no variation between particular qualities of a population and data-generating process.
- The alternate hypothesis asserts the existence of a distinction.
- Hypothesis testing allows you to reject the null hypothesis with a particular level of confidence.
- If the null hypothesis can be rejected, it lends support to the alternative hypothesis.
- The notion of falsity in science is founded on null hypothesis testing.

The formula is 4/3 times pi times radius cubed. The radius is 9. 4/3 is 1.33. 3.14 times 9 cubed is 81 times 3.14. That is 254.34. 1.33 times 254.34 is 338.2722. That rounds to 338.
Chose a fraction with a denometer of 8.
Ex: 3/8
To compare 5/6 and 3/8 we need to find the LCM (the lowest common denominator.)
This can easily be done by listing the multiples of each number.
6: 6, 12, 18, 24, 30, 36
8: 8, 16, 24, 32, 40, 48
The Lowest common denominator would be 24.
6*4=40
8*3=40
Since we altered the denometer, either by multyplying by 6 or 8 (to get 24), we must do the same for the numerator.
3/8*3
9/24
5/6*4
20/24
Now we compare the fraction properly.
20 is larger than 9 so we know that 3/8 is less than 5/6.
Hope this helps! Please leave a thanks/braniest answer!
Answer:
x=5
Step-by-step explanation:
Since the triangles are similar we can use ratios to solve
4.5 7.5
---- = ------
3 x
Using cross products
4.5x = 3 * 7.5
4.5x = 22.5
Divide each side by 4.5
x = 22.5/4.5
x=5
