paired t–test is used when there is one measurement variable and two nominal variables. The most common design is that one nominal variable represents individual organisms, while the other is "before" and "after" some treatment.
Answer:
a = 0.3
b = 0.4
c = 40%
d = 15%
Step-by-step explanation:
There are a total of 10 tick marks. So we know that 1 tick mark = 10%
a has 3 tick marks so you can say it's 0.3
b has 4 tick marks so you can say it's 0.4
c also has 4 tick marks, but it's asking for the percentage, so you get 40%
d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%
Your answer would be D. 225%. 9/4 equals to 2.25 which multiplied but a 100 to make the percentage equals 225%.
The correct answer is: [A]: " 8 √3 " .
