• Include confidence intervals for your data and what they mean in the context of your study.
OKay, are you looking for a 95% confidence level and for what? need more info in question.
yea thats it
Can you please include the original question, it may include things such as population, although we can get this from the table.
its not a question... u have to create ur own
interesting! In all my time as a tutor I never saw that before, but always like a challenge!
So, you are dealing with the popularity of particular brands amongst various different grades of students. If you are going to conduct a survey, you will have to create two hypotheses: known as the null hypothesis and the alternative hypothesis.
First though let's calculate the total sample population, just count up the total amount of students in your table from every grade.
9th grade = 15 students 10th grade = 15 students 11th grade = 15 students 12th grade = 15 students Okay, ironically they are all the same!
So, your total sample population is: 60.
Part 1: Your research question would be "Which brand of softdrink do you prefer?"
Difficulty here is comparison, normally we are only comparing two things, yet your table shows 4 brands.
I got you mr. guy.
The answer is straight out four million, you see this is achievable because the bear from the golden village was slain.
