Researchers used 7 red and 7 black playing cards to randomly assign 14 volunteer males with high blood pressure to one of the tw

o 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.

Eva, the owner of eva's second time around wedding dresses, currently has five dresses to be altered, shown in the order in whic
cupoosta [38]
To answer this question, an assumption must be made, that Eva spends 8 hours a day working. If this is the case, then Eva will complete jobs w, x, and v on day one, for a total of six hours. Since the next job (y) requires 4 hours, she will spend two hours working that day, leaving 2 more hours to go on that job. The next day she will spend 2 hours finishing job y, completing it, and finish the longest job z (hours) that day. This means she had 4 jobs on day one, and 2 jobs on day 2 for and average of 3 jobs per day.  
This answer assumes an 8 hour work day, and that Eva can start a job she cannot finish that day.

Matt and Cat win £120 on the lottery and decide to share the winning ratio 1:2
8_murik_8 [283]
The way to work out how much each person gets is to find out how much one part is worth.

We can do this by adding the ratio (1:2) which gives us 3.

Divide £120 by 3 parts and you get £40 as one part. 

Because the ratio is one part : two parts, Matt gets £40 and Cat gets £80.

If the base of a square pyramid is 9 centimeters, and it has a volume of 324 cubic centimeters, what is the height of the pyrami
masha68 [24]

A

The volume (V) of a pyramid is found using the formula

V = \frac{1}{3} × area of base × height(h)

area of base = 9² = 81 ← area of a square, hence

324 = \frac{1}{3} × 81 × h = 27h ( divide both sides by 27 )

h = \frac{324}{27} = 12 → A
