MATH 160 Cuyamaca College Hypothesis Test for a Population Mean Question
Module 22 - Hypothesis Test for a Population Mean (17 of 19 groupwork 3)New AttemptPromptIn a previous lab we tested the following hypotheses, H0H0: μ=4.73μ=4.73 and HaHa: μ<4.73μ<4.73 (where μμ is the mean number of alcoholic drinks consumed by students at a liberal arts college).In a random sample of 75 students, the mean was 3.93 alcoholic drinks consumed in a week. Here is the StatCrunch output from the hypothesis test.μμ: Mean of variableH0H0: μ=4.73μ=4.73HAHA: μ≠4.73μ≠4.73Hypothesis test resultsVariableSample MeanStd.

Which graph is used to check conditions? Why?What do we look for in the graph to verify that conditions are met?What else do we need to know about the sample of seeds before using the T-test?Use StatCrunch to find the T-score and the P-value. Hint: as you work through the StatCrunch directions, keep in mind that we want to calculate the differences as regular − kiln-dried . So you will choose Regular seed for Sample 1 and kiln-dried seed for Sample 2.

Statistical Analysis Report Worksheet
InstructionsYou are currently working at NCLEX Memorial Hospital in the Infectious Diseases Unit. Over the past few days, you have noticed an increase in patients admitted with a particular infectious disease. You believe that the ages of these patients play a critical role in the method used to treat the patients. You decide to speak to your manager, and together you work to use statistical analysis to look more closely at the ages of these patients.You do some research and put together a spreadsheet (attached) of the data that contains the following information:Client numberInfection disease statusAge of the patientYou are to put together a PowerPoint presentation that explains the analysis of your findings which you will submit to your manager. The presentation should contain all components of your findings. For review, the components of the report should include:Brief overview of the scenario and variables in the data setDiscussion, calculation, and interpretation of the mean, median, mode, range, standard deviation, and varianceDiscussion, construction, and interpretation of the 95% confidence intervalExplanation of the full hypothesis testConclusionThe calculations should be performed in your spreadsheet that you will also submit to your manager. You can find additional information on what to add to your PowerPoint presentation in this Word document (attached). Use the questions in the worksheet as your guide for the contents of your presentation.For your final deliverable, submit your PowerPoint presentation and the Excel workbook showing your work. MUST MEET THE FOLLOWING REQUIREMENTS! All problems are solved correctly. Complete and detailed steps are provided to explain how to solve the problem. Explanations demonstrate a mastery of understanding of the statistical concepts and terminology. All variables, equations, and expressions are properly formatted.

The quadratic formula is important in mathematics: it “can… be used to solve any quadratic equation” (Algebra for College Students, Section 6.4). Every student in an algebra course has to memorize this equation. Search the Internet for any tips, tricks, or shortcuts people use to remember the quadratic formula. Then, answer the questions here:Share your favorite new tip or trick you learned about.Explain why you selected this tip or trick. Describe why you think this tip or trick might work in helping other students remember the formula.Do you have your own tips or tricks you use when solving quadratic formulas? If so, share those as well.
