Please how so I construct 80% prediction interval for diastolic pressure of a particular person whose systolic is 115. Round three decimals

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 7 adults. The following table presents the results. The least-squares regression line y = bo+ bjx =8.3129 +0.5916x, s = 4.964092, E (x-x) =2936, and x = 126 are known for this Ed data.

Round your answer to at least three decimal places. The point estimate is 76.347
