This trial evaluated the fever reducing effects of three substances. Study subjects were adults seen in an emergency room with diagnosis of flu with body temperatures between 100.0 degrees F to 100.9 degree F. The three treatments aspirin, ibuprofen, and acetaminophen were assigned randomly to study subjects. Body temperatures were reevaluated 2 hours after administration of treatments. Display the above data with side-by-side box plots and calculates the mean and standard deviation of each group and describe what you find then produce an ANOVA for the problem. Conduct post hoc comparisons with the LSD method. Which groups differ significantly at α = 0.05?
Calculate the mean and standard deviation of each group.
Determine relative frequency of X=4? Generate the cumulative frequencies.
What is the probability that the team wins tonight and that there will be a large crowd at tomorrow's game?
Are you doubtful of any of these data points? if so why does there show to be a linear relation between degree of stenosis and nuber of reactive nuclei?
Make for more scatter plots comparing GDP growth 1970-2000 to corruption, political rights, rule of law, and socio-political instability
Make a forecast for 2004, using either the fitted trend model or a judgment forecast. Why is it best to ignore earlier years in this data set?
Distinct random variable
A study sponsored by American Express Co. and the French government tourist office found that old American stereotypes about French unfriendliness weren't true.
Create a hypothesis and perform a series of tests to determine if there is any fundamental difference in the findings.
Evaluate the mean wait time and throughput rate
Sampling variability refers to the idea that different samples will include different individuals
Is there evidence of violations of the usual ANOVA assumptions of equal variances and normal populations? Set up and perform appropriate TESTS at the α = 0.05 level of significance.
In this paragraph, be sure to make it clear how you handled the issue of conducting three planned comparisons. Also provide the ANOVA summary table for these results.
