Answer: t = 1.9287
Step-by-step explanation:
Let be the average number of pages should be sent by 2-day mail instead.
As per given we have,
Sample mean :
Sample standard deviation : s=3.81
sample size : n= 24
Since , the sample size is less than 30 and populations standard deviation is unknown , so we use t-test.
The test statistic for population mean :-
Hence, the test statistics : t = 1.9287
This is the answer!!!!!!!
Answer:
2
Step-by-step explanation:
2x2= 4
4/2=2
Because for a fraction with a small denominator, you don't have to split them up into small pieces and as many pieces. For example: let's say you had 2/3. you draw a circle with 3 equal quadrants. Those quadrants are big because you didn't have to split the circle up into a lot of peices; only 3.
Now for a bigger denominator like 20/32, you have to split the circle into 32 peices. For all of them to fit, you have to make the pieces small.
