PLEASE NEED THIS ASSAP. THANKS IN ADVANCE

SCENARIO 1 The Florida Department of Health studied smokers in the state of Florida. They recruited participants by putting an ad on social media targeting smokers in who live in Florida. They were able to study a total 1,500 eligible participants. Their research question was: How does the number of cigarettes smoked per week impact the number of minutes run continuously on a treadmill?

1. What is the n value of this study? ______________________

2.What is the populationof interest in this study?

________________________________________________________________________

3.What type of sampling method is used in this study?

________________________________________________________________________

4.What type of data is used in this study (interval, nominal, or ordinal)?

________________________________________________________________________

5.How many variables are there in this study? What are they?

________________________________________________________________________

6.How many groups of participants are in this study? __________________________

7.Is this study measuring differences between means? (Yes/No) _________________

8.Is this study measuring a relationship between two or more variables? (Yes/No) ________

After their study ended, the Florida Department of Health released the following data table.

	Mean	Median	Mode
# of Cigarettes per Week	14	14	14
# of Minutes on Treadmill	7	6	5

9.Using this data table, draw what you think the distributionmight look like for each variable. You should have a total of 2 distributions: one for number of cigarettes and one for number of minutes on a treadmill.

10.How would you describe these distributions? (For example, are they normal, are they positively skewed, are they negatively skewed?)

SCENARIO 3 In another smoking study released by the Florida Department of Health, the researchers conducted a t-test examining how many cigarettes were smoked by a group of younger smokers (20-35 years old) versus a group of older smokers (36-60 years old). They got the following results.

	t	df	Sig. (2-tailed)
Pair 1 Older Group & Younger Group	5.687	299	.017

16.Can we reject the null hypothesis in this study? (Yes or No) Explain why or why not.
