Answer:
Comparing means from dependent samples.
Step-by-step explanation:
In the scenario described above, the 25 sampled individuals were used to test the effect of weightlifting on alleviating back pain. The samples used were not changed nor altered during the study as the same subjects who were tested to measure their level of pain before lifting weight were the same group subjected to the actual weight lifting test and again had their level of pain tested. Since only one group was involved in the study ( a single group was tested on neutral and actual treatment). Hence, the study used dependent samples to compare the average level of pain.
The answer is to the question is D
Answer:
75 times.
Step-by-step explanation:
Well there are 12 months and 3 of them start with the letter J, so theoretically, 25% of the months chosen will start with the letter J because 
, which is 25%. 25% of 300 (or 
, for those who like fractions) is 75, so theoretically, we can expect a month that starts with the letter J 75 times.
Hope this helps!

Answer:
The correct answer is B) 1555.6
Step-by-step explanation:
In order to find this, we must divide the part by the percentage. This will give us the total out of 100%
140/.09 = 1555.6
<u>Answer</u>
F(a+2) = (3a+11)/(a+2)
<u>Explanation</u>
F(x) = (3x + 5)/x
If you are to find F(a+2), you replace x with (a+2)
F(a+2) = (3(a+2)+5))/(a+2)
= (3a+6+5)/(a+2)
=(3a+11)/(a+2)
