 In response to your peers, explain why you think their original hypothesis statements are correct or not, the worded version and the statistical notation version, and whether the worded version matches the statistical notation version. Explain your reasoning. Then, see if you agree with their alternative wording and propose a third, worded version containing the […]

 With the data uploaded into StatCrunch (see the Module One non-graded StatCrunch activity for more information) and the health question you will explore identified, it is time to complete the following tasks: Describe the data set using summary statistics. Identify any limitations you think the data has. Identify the variables you will use in your […]

Please do worksheet attached 3-2 Problem Set Helps Remember all steps and the calculations must be shown (or StatCrunch output), or full points will not be given for the problem.  Just writing down the answer is not sufficient. You can type them into a word document,  write them out by hand, scan them, or take […]

 In this module, you have learned about two of the most frequently used probability distributions in biostatistics: the binomial and normal distributions. The binomial distribution and the normal distribution are similar in several ways. In fact, under certain conditions, the normal distribution is used to approximate the binomial. For your initial post, discuss the following […]

  Google your state’s Powerball or megamillions and calculate the probability of winning the jackpot. Most sites report odds instead of probability, so you’ll need to do a simple conversion.  Share a link that takes us to the odds information on your state’s Powerball or megamillions. – (My state is Virginia) In your original post, […]

 This journal is an opportunity to discuss the merits of the articles you selected from the list provided. Your journal response needs to relate to the content in the course and to your personal and professional experiences, and specifically answer the following: What topic or health question did you research, and why is it relevant […]

 This problem set assignment will involve activities designed to solidify the concepts learned in both Modules One and Two. Problems will be similar to those you will face in Module Four and will include one or two real-world applications to prepare you to think like a biostatistician. Check the module resource list to see which […]

   Pick one of the articles on the Gallup website OR choose one of the articles listed below for your degree field and discuss one or two of the results (there will be a lot, so do not feel the need to discuss them all). Stephenson, S. (2020, October 14). Educators Say Computer Science Lifts […]

 When responding to your peers, let them know if you agree or disagree with their assessment of the precision/reliability and validity of their measuring tool/method of measurement. Provide another tool that they could use to measure whatever they chose and discuss whether it is more or less precise and valid than their measuring tool. 

Two fair dice, one blue and one red, are tossed, and the up face on each die is recorded. Define the following events: E:E: {{ The numbers are equal }} F:F: {{ The difference of the numbers is 3 or more }} Find the following probabilities: P(E)=P(E)=16 P(F)=P(F)=12 P(EandF)=P(EandF)=112 P(E|F)=P(E|F)= P(F|E)=P(F|E)= Are events E and […]
