If anyone could help me with this I would be really greatful.
The mean of American women in their early twenties is about 64.5 inches and the standard deviation is about 2.5 inches. The mean heigh of me the same age is about 68.5 inches, with standard deviation about 2.7 inches. If the correlation between the heights of husbands and wives is about r = 0.5, what is the slop of the regression line of the husband's height in young couples? Draw a graph of the regressionline. Predict the height of the husband of a woman who is 67 inches tall.
How does one go about finding the slope and the y intercept in order to get the y hat = a + bx equation?
