Which statistical test to use to compare an antibiotic used on two different organisms? (i.e. Streptomycin was used on e.coli and s.aureus and we want to check if it's more significant on e.coli/s.aureus)
Answer: In this problem we will use Two-Way ANOVA Statistical test to compare an antibiotic used on two different organism.
Here we have two different categorical variables in likes of a) antibiotic b) organism respectively.
Then we have to see the interaction effect of antibiotic on two different organism ( e.coli and s.aureus) are significant or not by using F-statistics value .

Which of the following is a characteristic of antibiotic use in livestock? Development of antibiotic-resistant organisms is very rare. Proper cooking of the meat destroys any traces of antibiotics. Farmers use more than 5 times more antibiotic in livestock than physicians use in people. Because the antibiotics have a short half-life, the FDA permits slaughter of the animals at any time. There is no evidence of harm to the environment or human health from the use of antibiotics in livestock.

Two hospital emergency rooms use different procedures for triage of their patients. We want to test the claim that the mean waiting time of patients is the same for Clovis Hospital (C) and Fresno Hospital (F). We want to test whether there is a significant difference in the mean waiting time between the two hospitals ( μC -μF ¹ 0). With 0.001 level of significance and p-value of 1.47E-22 (approximately 0.0000), what do you conclude about the waiting time for...
We want to compare two different variances from a normally distributed sample that are independent of each other. What test should we use? Chi square, Linear regression, F-ratio, or Two-way ANOVA?
Castaneda v. Partida is an important court case in which statistical methods were used as part of a legal argument. When reviewing this case, the Supreme Court used the phrase "two or three standard deviations" as a criterion for statistical significance. This Supreme Court review has served as the basis for many subsequent applications of statistical methods in legal settings. (The two or three standard deviations referred to by the Court are values of the z statistic and correspond to...
Based on the following description, select the most appropriate statistical analysis to conduct, i.e. which test or procedure should you use to answer the posed scientific question: You wish to determine if the body temperature of your lab rabbits and their weight are related to each other.

3. Compare the fits of Equations 26 and 27 using the F-test. If the two equations are significantly different in overall fit, we can conclude that it's likely that Equation 26 is misspecified While the Ramsey RESET test is fairly easy to use, it does little more than signal when a major specification error might exist. If you encounter a sig nificant Ramsey RESET test, then you face the daunting task of figuring out exactly what the error is! Thus,...
