Question
You may need to use the appropriate technology to answer this question A sample of nie days over the past six months showed that a dentist treated the following numbers of patients at his dental clinic: 21, 24, 19, 18, 15, 21, 23, 18, and 26. If the number of patients sen per day is normally distributed, would an analysis of these sample data reject the hypothesis that the variance in the number of patients se per day is equal to 10? Use a 0.10 level of significance State the null and alternative hypotheses 0²10 Ha² 10 0²10 <10 0-10 H₂² 10 0²10 H 103 010 H30 Find the value of the test statistic (Hind your answer to three decimal places) Find the value (snd your awer to four decimal places) produ b State your cohesion Reject We can conclude that the variance in the munber of patients seen per ilay is not equal to 10.
