Department of Education was analysing the average mathematics test score in the schools in Victoria. It noticed that there were dramatic differences in scores among the schools. In the attempt to improve the scores of all the schools, department attempted to determine the factors that account for the differences. Accordingly, they took a random sample of 40 schools across the state and for each determined the mean test score last year, the percentage of teachers in the schools who have at least one university degree in mathematics, the mean age and the mean annual income of the mathematics teachers. The following is regression output from Excel.               SUMMARY OUTPUT                     Regression Statistics         Multiple R 0.597512         R Square 0.357021         Adjusted R Square 0.303439         Standard Error 7.724526         Observations 40                     ANOVA             df SS MS F Significance F…

GMU uses a robot food delivery service which now has been utilized in the City of Fairfax. One of the potential benefits of this service is to help the busiest students eat breakfast. Research has shown that about 80% of college students skip breakfast due to busy schedules and other reasons. Initial data were collected from a random sample of 595 Mason students who utilize the robot food delivery service and are presented in StatCrunch.    Show the full calculation of the sample proportion by including the number of students who skipped breakfast, the total number of students sampled, and the value of the sample proportion. Present this sample proportion as a decimal rounded to four decimal places. Frequency table results for Breakfast?Count = 595 Breakfast?

Some sleep experts believe that sleep apnea is more in men than in the general population. In other words, they claim that the percentage of men who suffer from sleep apnea is greater than 8% (which is the percent believed to affect the population in general).  To test this claim, one sleep expert interviews 50 men and determines that 7 of these men suffer from sleep apnea.  Does this evidence support the claim at that the percentage of men who suffer from sleep apnea is more than 8%?  Use a 0.02 level of significance What are the hypotheses?         What is the test statistic? Is it a z or a t?         Find the P-value for this test statistic. How does it compare to the significance level?  On the normal curve, indicate the location of the test statistic  and  the p-value. (label them on the graph)                 Write a conclusion in statistical terms and relate it to the parameters of this problem.           Note:  The following is not a hypothesis test, but rather a…
