Answer:
B. A teacher compares the pre-test and post-test scores of students
Step-by-step explanation:
the answer is true, because it is a good example to compare the tests between students, we know that a matching pair design is a random model and is used when the experiment allows grouping subjects in pairs based on a variable and each pair will receive randomly a different handling, the answer A is not true because in the example all students are uniformly averaged and the variable is not correlated with subgroups, option c is incorrect because the variable was not randomized and generates classification bias and the option d is incorrect because the teacher compares a small sample as her class with a score of a total sample, but does not intervene on her students when selecting the corresponding group
31/50 is the correct answer. It began at 62/100 but you must reduce
One way to approach this is to know that $5200 is 80% of her savings, so if we divide 5200 by 8 we will get 10% of her savings. 5200/8 = $650.
We can then multiply this by 10 to get 100%, or her total, savings (because 10*10=100)
So, $650*10= $6500
The total savings in dollars is $6500
