When using a two sample test of means with equal standard deviations, then T distribution is the best option for it.
Sample test:
Sample test refers a method of reaching a conclusion to reject or support the claims based on sample data.
Given,
Here we need to identify in which of the following are assumptions made when using a two sample test of means with equal standard deviations.
While we looking into the options for this one, then we have identified that, the sampling distribution of the difference of means is a T distribution.
So, the populations have equal but unknown standard deviation's.
Therefore, we "pool" the sample standard deviation.

Answer:
you would have to find the other value of the ratio.
If you look at the original ratio of 5:4, you can tell that 45 is just 8×5 and therefore you can also multiply 4×8 which would 32.
Step-by-step explanation:
I hope this helps :)

Answer:
I have made it in above figure
The quantity of pounds of pencils that Jason gets, based on his sharing ratio, is <u>0.15 pounds</u>.
<h3>What is the sharing ratio?</h3>
The sharing ratio is the percentage or ratio that is held by a person out of the total value of the thing being shared.
Jason's share of the pencil can be determined by multiplying the total pencils in the box (1.5 x ¹/₂) by Jason's sharing ratio (¹/₅).
<h3>Data and Calculations:</h3>
Quantity of pencils bought = 1.5 pounds
Half of the pencils in a box = 0.75 pounds (1.5 x ¹/₂)
The pounds got by Jason from the box = <u>0.15 </u>(0.75 x ¹/₅)
Thus, the quantity of pounds of pencils that Jason gets is <u>0.15 pounds</u>.
