An investigator makes a chi-square test, to see whether the observed frequencies are too far from the expected frequencies. If there are 8 degrees of freedom, the p-value will be bigger with x2 = [ Select ] than with x ? = 13 Question 5 3 pts The area to the right of 20.48 under the chi-square curve with 10 degrees of freedom is (Fill in the numerical value. Round to three decimal places) A study attempted to establish a linear relationship between IQ score and musical aptitude.
