A study showed that low-intensity vibration therapy reduces pain levels in patients with fibromyalgia. During each session in th

e study, vibration pads were placed on the pain
site indicated by the patient. Pain reduction was measured through self-reporting after each session.
Another study is being designed to examine whether low-intensity vibration therapy also reduces pain in patients suffering from ruptured disks in the lumbar region of the back.
Three hundred male patients are subjects in the new study.
Part A: What is an appropriate design for the new study? Include treatments used, method of treatment assignment, and variables that should be measured. (4 points)
Part B: If the study consisted of 150 male and 150 female patients instead of 300 male patients, would you change the study design? If so, how would you modify your design
? If not, why not? (4 points)
Part C: Could your design be double-blind? Explain. (2 points)

A study showed that low-intensity vibration therapy reduces pain levels in patients with fibromyalgia. What is an appropriate design for the new study? If the study consisted of 150 male and 150 female patients instead of 300 male patients?, as well as  Could your design be double-blind? are explained as

1) To get around the placebo effect, it is recommended that vibration pads be applied to the area of discomfort and that pain be measured objectively using instruments, rather than via subjective reporting. Time spent in treatment, preexisting pain levels, post-vibration pain levels throughout the day, and total daily pain intensity should all be tracked, as well as the individuals' ages.

2) To avoid any potential bias in the findings, we would split the sample evenly between male and female individuals (150 total) and use them in both the control and experimental groups (150 total).

3) Since the placebo effect may be introduced by revealing to either the subjects or the experimenters which group each individual is a part of, our design would indeed be double-blind.

It is required to make 14 grams of certain chemical compound called Z. This is made from compounds W, X, and Y in the ratio of 2
dexar [7]

Answer:

W = 9.33 grams

X = 4.67 grams

Step-by-step explanation:

Given;

Mass of Z to be made = 14 grams

Composition of Z

W:X:Y = 2:1:3

To make 6 grams of Y requires 4 grams of W and 2 grams of X

Composition of Y (for 6grams)

W:X = 4:2 = 2:1

Substituting the composition of Y to Z

Z = W:X:Y = 2:1:3

Z = W:X:W:X = 2:1:2:1

summing them up, we have;

Z = W:X = 4:2 = 2:1

Since the final mixing ratio for W and X are 2:1, to make 14 grams of Z, we need;

W = 2/3 × 14grams = 28/3 grams

W = 9.33 grams

X = 1/3 × 14grams = 14/3 grams

X = 4.67 grams

A radioactive isotope has a half life of 4.51 days. If 12.63 grams are now present, how much will be left after 15
Marizza181 [45]

Answer:

Step-by-step explanation:

f=ir^t\\ \\ \frac{1}{2}=r^{4.51}\\ \\ ln(0.5)=4.51lnr\\ \\ r=e^{\frac{ln0.5}{4.51}}\\ \\ r\approx 0.8575\\ \\ f(15)=12.63(0.8575^{15}\\ \\ f(15)\approx 1.26g
