Answer: 8
Step-by-step explanation:
The formula to find the t-test statistic for differences between in two population mean:-
,where = sample mean difference
SE= Sample error
Given : SE= 4 points
t-statistic = 2.00
Substitute theses values in the above formula , we get
Hence, the sample mean difference is
Answer:

Answer:
Step-by-step explanation:
<u>The distance is the absolute value of the difference of the coordinates:</u>
- 2 2/5 - (-4 3/4) =
- 2 2/5 + 4 3/4 =
- 6 + 2/5 + 3/4 =
- 6 + 8/20 + 15/20 =
- 6 23/20 =
- 7 3/20
