Project Part 4
The final part of your project is described in the following documents.
Here is a Microsoft Word Doc with the description: Last Project Math 13-1.docx
I UPDATED the assignment here. I deleted a question
Here is the Google Doc Description
Here is a completed sample project submitted by a past student.
Your Tasks:
Choose one of your numerical data sets to construct a 90% confidence interval about a population mean. (Lesson 4.2 TOD) -OR- Choose a categorical data and pick ONE of your categories to construct a 90% confidence interval for that proportion. (Lesson 3.2 TOD) “We are 90% confident…
Choose one of your categorical data sets to complete a hypothesis test about a population proportion. Use α=0.05 What is your claim? Use this at Ha below. (Lesson 3.4 TOD)
Choose one of your numerical data sets, separate it by gender, then complete a hypothesis test for the claim that the mean for men differs from the mean for women. Use α=0.10 (Lesson 5.6 TOD)
Choose two lists of numerical data you collected that may be related and make a scatterplot. Then compute the LSRL in Desmos (y1~a+bx1) and identify the correlation coefficient, r= ? Describe the Form, Direction, and Strength of the correlation in your scatterplot. (Lesson 6.2 and 6.3 TOD)
Directions:
After you have completed your confidence interval and your hypothesis test you will complete a summary report. Your report may be typed, or handwritten, or in a google doc. In your report please include the following:
Title
Abstract – this is a summary of your report
Confidence Interval with sentence conclusion
Hypothesis test with sentence conclusion
Summarize how you collected your sample data and how you tried to make it as unbiased as possible so that it would represent all peopl in the population.
What went wrong or not as you expected?
In a future research project, what would you recommend to improve the research project to make it more valid? – there is ALWAYS room for improvement. Don’t say “nothing”
Project Part 3 (Due by April 23)
It is time to start collecting your data! Talk to at least 30 people and interview them with the survey questions you created. Collect the data using a google form (video tutorial) or using a google sheet as shown below:
