statistics help 15) Express the alternative hypothesis in symbolic form. A professor dlaims that the mean amount of time (in hours) sophomores spent studying for the statistics final exam is more than that of freshmen. Assume that the two samples are independent. Let the freshmen be the first population and the sophomores be the second 16) Assume that the following confidence interval for the difference in the mean length of male (sample 1) and birth was constructed using independent simple...

Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. The table below shows the heights (in feet) and the number of stories of six notable buildings in a city. Height comma xHeight, x 764 625 520 510 492...
