Answer:
Step-by-step explanation:
(a) The type of study described in the question is referred to as an experimental study.
(b) The treatment group is the group that exercises 2 times a week, whereas the control group is the group that does not exercise.
(c) Yes, the study under consideration makes use of blocking.
The blocking variables are 18-30-year-olds, 31-40-year-olds, and 41-55year olds.
(d) No, the study under consideration did not make use of blinding because the patients know if they are in the group that exercises or the one that doesn’t.
First we have to find out the total. So we do 88 x 4 = 352 since it will give us the the total score when all of the scores are added.Then we add 74+94+86 which equals 254. And then 352 - 254 = 100 and that would be Ethan's score
Answer:
an equation
Step-by-step explanation:
A mathematical statement that two expressions are equal is called an equation.
The word "equation" comes from the same root as "equality"... so is two sides of an expression are of equal values, they form an equation, like A = B.
When both sides of a statement are not equal to each other, that is an inequality, meaning NOT equal, like A > B.
Answer:
The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.
Step-by-step explanation:
Given that:
The treatment group using Spray A reported a mean of 3.5 mosquito bites.
The treatment group using Spray B reported a mean of 5.6 mosquito bites.
After the data are re-randomized; the differences of the means are shown in the dot plot. The dot plot is attached in the file below;
The best conclusion that can be make based on the data from the dot plot is :
The difference of the means is not significant because the re-randomizations show that it is within the range of what could happen by chance.
