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 =
