Researchers used 7 red and 7 black playing cards to randomly assign 14 volunteer males with high blood pressure to one of the two diets for four weeks. The two diets are: a fish oil diet and a standard oil diet. The reductions in diastolic blood pressure were measured in mmHg. Label the fish oil diet group 1 and the standard oil diet 2. Now since the measurements are the reductions in blood pressure for each man, it is of interest to know whether the mean reduction is zero for each group. For the regular oil diet group do the following:

(a) Compute the average and standard deviation. What are the degrees of freedom associated with the sample standard deviation, s2?
(b) Compute the standard error for the average from this group, SE(Y2).
(c) Construct a 95% confidence interval for Mu2.
(d) For the hypothesis that Mu2 is zero, compute the t-test statistic Y2/SE(Y2). Find the two-sided P-value as the proportion of values from the appropriate t-distribution farther from 0 than this value.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
