Question

Salt-free diets are often prescribed to people with high blood pressure. The following data values were obtained from an experiment designed to estimate the reduction in diastolic blood pressure as a result of consuming a salt-free diet for 2 weeks. Assume diastolic readings to be normally distributed. (a) Is there evidence that diastolic blood pressure is reduced by having salt-free diets? Use alpha = 0.05. (b) Construct the 95% confidence interval for the difference in the mean blood pressures.

Answer 1

Answer:

Hy friend, thanx for asking the question...

Here's ur ans....

9025

5×5×19×19

We hv a pair of 5 and a pair of 19

Take one 5 and one 19 from it,

That is,

5×19

95

\sqrt{9025 } = \: 95

9025

=95

Hope it helped u...
