## R command
Before=c(70,80,72,76,76,76,72,78,82,64,74,92,74,68,84)
After=c(68,72,62,70,58,67,68,59,66,72,74,65,74,72,73)
## a) The 95% Confidence interval include in output of this
test
t.test(x=Before, y =After, alternative = "greater", paired
=TRUE,
conf.level = 0.95)
## End
Let, d=Before=After
Hypothesis
The 95% confidence interval for the true population mean reduction in blood pressure is (3.580296, infinity). Hence, the true population mean reduction in blood pressure falls in this interval with 95% confidence.
b) The p-value of the test is 0.003009 and less than 0.01 significance level. Hence, we can reject the null hypothesis and accept the claim that the pill has the undesirable side effect of reducing the blood pressure of the user at the 0.01 significance level.

Please write the R code to solve the question. Problem (2). In an effort to link cold environments with hypertension in humans, a preliminary experiment was conducted to investigate the effect of cold on hypertension in rats. Two random samples of 6 rats each were exposed to different environments. One sample of rats were held in a normal environment at 26°C. The other sample was held in a cold 5°C environment. Blood pressures and heart rates were measured for rats...
