A European football agency reports the following based on a study they did: 90% of soccer players take magnesium in topical form for muscle soreness, 5.5% take magnesium in pill form, and 4.5% take magnesium in powder form. To verify, a researcher randomly selects 794 soccer players and reports the following.  Form of magnesium (Mg) Number of soccer players  Topical 632 Pill 95 Powder 67   To determine if the proportions the European football agency reported are accurate, the researcher will conduct a Chi-square Goodness of Fit test. Complete the table below to calculate the chi-square statistic. Round all values to two decimal places! (Use the correct expected counts from the previous question.)   Form Topical Pill Powder Observed Count 632 95 67 Observed - Expected       (Observed - Expected)2       (Observed - Expected)2/Expected         X2 - statistic = The degrees of freedom for the chi-square statistic =

You will be applying what you have learned in this course by gathering data and running a statistical analysis.    1) To study about the relationship between height and the weight, you need to collect a sample of nine (9) people using a systematic sampling method. a. What is the population of people? b.Where and how are you going to collect your sample? c. Does your sample accurately represent your population? Why or why not? d. Collect the sample and record the data. 2) (CLO 1) Construct a confidence interval to estimate the mean height and the mean weight by completing the following: a. Find the sample mean and the sample standard deviation of the height. b. Find the sample mean and the sample standard deviation of the weight. c. Construct and interpret a confidence interval to estimate the mean height. d. Construct and interpret a confidence interval to estimate the mean weight. 3) (CLO 2) Test a claim that the mean height of people you know is not equal to 64 inches using the…
