Run a regression analysis on the following bivariate set of data with y as the response variable. X y 55.1 77.5 65.1 77.7 48 78.1 72.2 72.8 54.4 74.4 74.4 71.7 62.2 72.5 73.5 71.7 67.4 74.6 66.5 69.3 58.2 74.3 65.9 75.4 68.6 72.8 70.3 75.2 70.4 72.1 Verify that the correlation is significant at an o = 0.05. If the correlation is indeed significant, predict what value (on average) for the explanatory variable will give you a value of 70 on the response variable. What is the predicted explanatory value? X = (Report answer accurate to one decimal place.)
