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
Answer:
<u>27 x 2 </u> = <u>54 </u> = 54% 54% of racers finished in less than 57 minutes
50 x 2 = 100 =
To solve this problem you must apply the proccedure shown below:
1. You need to apply the Pythagorean Theorem:
Where <em>c</em> is the hypotenuse and the legs are<em> a</em> and <em>b.</em>
2. Now, you must substitute the values given in the problem above and solve for <em>b</em>:
Therefore, the answer is: The value of <em>b</em> is 6.92
