(1)Suppose you are testing whether or not a new net leads to a significant increase in bycatch, but you want to be species-specific. Thus, you would like to know whether or not the new net leads to a significant increase in the bycatch for each of five species individually. If your desired significance level over the 5 tests is 1%, what does the Bonferroni correction state you should set the individual significance levels at? Answer in percent and round to the nearest tenth (e.g. record 3.33% as 3.3).

(2)What is the standard error for the sampling distribution of correlation coefficients when the sample size is 67 and the standard deviations of each of the two random variables are 6.4 and 8.1 respectively? Round your answer to the nearest thousandth.

(3)Convert r = 0.55 to its z\'-score using Fisher’s transformation. Round your answer to the nearest thousandth.

(4)Using Fisher’s transformation, what would the z-score in N(0,1) be for a sample size of 52 with r = 0.7 when the sampling distribution has been centered at the population correlation of rho = 0.25? Round your answer to the nearest hundredth.

Can you help me with these 4 questions and show me process? Many thanks!!!

Solution

1. Alpha=0.01/5=0.002.

3. z=0.6184 [Just substitute the value of r in the equation, Z_r=(1/2)[log_e(1+r)-log_e[1-r]

4.0.8673
