Which of the following best describes the meaning of a p value for a chi squared score? a) A p value is another way to look at a chi squared score, so a low p value is essentially the same thing as a low chi squared score. b) A low p value means that the data is not likely to show any pattern or correlation. c)The higher the chi squared score, the lower the p value, because high chi squared scores mean the data looks like random data. d)A higher chi squared score means that the data was different from expected, and therefore unlikely to have occurred by chance.

A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights (in centimeters) of randomly selected presidents along with the heights of their main opponents. Complete parts (a) and (b) below.

Use the sample data with a 0.05 significance level to test the claim that for the population of heights for presidents and their main opponents, the differences have a mean greater than 0 cm. In this example, Ha is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the president's height minus their main opponent's height. What are the null and alternative hypotheses for the hypothesis test? Họ: Ha cm H1: Hd cm (Type integers or decimals. Do not round.)
