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.

Last month, when Joe took his puppy to the veterinarian, the puppy weighed 5.4 pounds. This month, the puppy weighed 7.56 pounds
tino4ka555 [31]

<u>Answer:</u>

40%

<u>Step-by-step explanation:</u>

We are given that last month, Joe's puppy weight 5.4 pounds while this month, the puppy weighed 7.56 pounds.

We are to find the percentage increase of the weight of the puppy

We know that the formula of percentage increase if given by:

<em>Percentage increase = (new value - initial value)/initial value × 100</em>

So substituting the given values to get:

Percentage increase in puppy's weight = \frac{7.56-5.4}{5.4} \times 100 = 40%

36, ___, ___, 32/3 is a geometric sequence, with some terms missing. First, please solve for "r", the common ratio between each
Ksju [112]

Answer: r = 2/3

Step-by-step explanation:

In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the information given,

a = 36

The 4th term is 32/3

n = 4

Therefore,

T4 = 32/3 = 36 × r^(4 - 1)

32/3 = 36 × r^3

Dividing both sides if the equation by 36, it becomes

32/3 × 1/36 = r^3

8/27 = r^3

Taking cube root of both sides of the equation, it becomes

(8/27)^1/3 = r^3 × 1/3

r = 2/3
