Question
In the significance test of a correlation coefficient, state the null hypothesis. Use as few words as possible. In a mouse model a drug dose (x) of 0.1.2 and 5 mg/day was given in food. As the response, percent change in body weight (y) was measured after one week. Using strict statistical reasoning, what correlation method should be used? insert the single best answer a-i Spearman Bootstrap Permutation Kendall Pearson Monte Carlo kernel density power analysis none of the above There are two major statistical methods for calculating confidence intervals (CI) for correlation coefficients. We enabled these methods in R in class. As your answer, insert one to several words such that the question then reads as a proper sentence; the names of R functions are not the answers. The traditional (classical) method uses to calculate CI of correlation coefficients. The computationally intensive method uses to calculate CI of correlation coefficients.Explanation / Answer
2) For correlation, the null hypothesis is that r = 0 --
that there is no relationship between the variables.
