Answer:
When conducting an analysis of variance analysis on a set of samples and the null hypothesis is rejected, we can test for the difference between treatment can be tested with the aid of a t-test. This is employed when 2 related groups are involved. Independent sample, paired sample or one-sample t-test can be conducted.
Step-by-step explanation:
A t-test is a test statistic used to make inferences that determine the differences that exist statistically between 2 related groups. It tells us if the 2 groups tested are from the same population. There are 3 types of t-test namely independent sample t-test, paired-sample t-test and one-sample t-test

Answer:
The length of new ramp is 49.03 ft.
Step-by-step explanation:
It is given that 26 ft long ramp is used to reach 10 ft up a wall. The ramp covers a horizontal distance of 24 ft.
If the horizontal distance is doubled, then the horizontal distance is 48 ft. The height remains same. Therefore the height of ram is 10 ft.
Use pythagoras in new right angle triangle.
Therefore the length of new ramp is 49.03 ft.
Answer: The correct choice for this problem is answer D.
In the beginning Azul is describing probability with a number cube. A number cube has 6 possibilities. He labels 4 of them as favorable, 4/6 or 2/3. He labels 2 of them unfavorable, 2/6 or 1/3.
Choice D is the only choice that has a matching probability of 2/3.
