In order to investigate if the systolic blood pressure measurements vary in standing and lying positions the systolic blood pressure levels of a sample of 12 persons were measured in both positions (first in standing position and then in lying position). The data of this experiment are recorded in SSPS file.

  1. A researcher believes the mean systolic blood pressure level in standing position is more than that in lying position. Test the appropriate hypothesis to investigate the researcher’s belief at alpha=0.05.
  1. Find the 95% confidence interval for the difference in mean systolic blood pressure levels in two positions. Interpret the result.

Please mentioned the steps in SPSS and screen shoot of it

The table is for the data.

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d = (blood pressure before taking new drug) − (blood pressure after taking new drug). Use a significance level of α = 0.05 for the test. Assume that the...
