In: Statistics and Probability

Test to see if the population correlation coefficient is not equal to zero using significance of 0.05. What are your conclusions?

Consider the following

X:            4              7              2              6              6

Y:            6              9              5              5              7

Using XLS, calculate the correlation coefficient for this sample. Test to see if the population correlation coefficient is not equal to zero using significance of 0.05. What are your conclusions?

True or False? A hypothesis test is conducted at to test whether the population correlation coefficient is zero. If the sample size is 25 and the sample correlation coefficient is 0.6, then the critical values of the student t that define the upper and lower tail rejection areas are 2.069 and -2.069, respectively.

test the hypothesis (α = 0.05) that the population proportions of red and brown are equal (pred = pbrown). You are testing if their proportions are equal to one another. NOTE: These are NOT independent samples, but we will use this approach anyway to practice the method. This also means that n1 and n2 will both be the total number of candies in all the bags. The “x” values for red and brown are the counts of each we found...
