Answer:
C. The samples are independent because there is not a natural pairing between the two samples.
Step-by-step explanation:
Independent samples are stand-alone samples. Their values do not give information about other values in another samples. They cannot be altered. Examples: To test the effectiveness of a particular drug in managing diabetes, a group of people is placed on the active drug. Another group is placed on a placebo. The two samples are independent because their values are taken from two different set of groups or people.
But a dependent sample is usually taken from the same group to test for the effectiveness of a drug before and after treatment.
25/125 is
simplified to 1/5
decimal form 0.2
percent 20%
(to get from decimal to percentage multiply the number by 100 or move the decimal point two places to the right)
