Does the number of commercials shown during a half-hour television program affect how viewers rate the show? In a preliminary study eight people were asked to watch a pilot for a situation comedy and rate the show (1 = Terrible, 2 = Bad, 3 = OK, 4 = Good, 5 = Very good). Each person was shown a different number of 30-second commercials. The data are shown here. Calculate the Spearman rank correlation coefficient and test with a 10% significance level to determine whether there is a relationship between the two variables.
