Suppose we examined medical records of 500 individuals admitted to the hospital, and we cross-classified them by whether they had lung disease or some other disease and the number of cigs they smoked daily. The individuals in the sample were distributed as follows 1.What proportion of the sample both had lung cancer and smoked 25 or more cigs per day? 2.Of all individuals who had lung cancer, what proportion smoked fewer than 25 cigs per day? 3.What proportion of individuals in the sample smoked fewer than 25 cigs per day?

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters, for a sample of 8 adults. The following table presents the results. Systolic Diastolic 125 85 108 85 103 78 114 78 119 67 118 88 131 75 116 71 Send data to Excel The least-squares regression line y = b,+b,x= 89.6478 – 0.0966x and E (x-x) = 551.5000 are known for this data. Use the critical value method to test H,: B, = 0 versus H, : B, <0. Can you conclude that systolic blood pressure is useful in predicting diastolic blood pressure?
