A sample of five individuals was considered to determine if their systolic blood pressure varied when measured with analog and digital equipment. Follow- ing are the readings on their systolic blood pressures (in mmHg). Analog: 121, 126, 128, 123, 127 Digital: 120, 127, 127, 121, 128 Assuming that the populations are normal, test at the 0.05 level of significance whether the two methods of measurements give, on average, the same result.
