A study compared surgery and splinting for subjects suffering from carpal tunnel syndrome. It was found that among 73 patients treated with surgery,there was a 92% success rate. Among 83 patients treated with splints, there was a 72% success rate.

Answers

Answer:

-4.317

Step-by-step explanation:

The z test statistic for testing of 1-proportion can be computed as

$z=\frac{phat-p}{\sqrt{(pq)/(n) } }$

We know that

phat=x/n.

We know that x=40 and n=120.

Thus,

phat=40/120=0.3333

p=hypothesized proportion=0.53

q=1-p=1-0.53=0.47

So, required z-statistic is

$z=\frac{0.3333-0.53}{\sqrt{(0.53(0.47))/(120) } }$

$z=(-0.1967)/( 0.04556 )$

z=-4.317.

Thus, the required test statistic value for given hypothesis is z=-4.317.

What is the difference x +5/ x +2 - x + 1/x ^2 + 2x?

Answers

ANSWER
The difference is,

$\frac{ {x}^(2) + 4x - 1}{ {x}^(2) + 2x}$

EXPLANATION

To find the difference, we just have to simplify the expression.

The given expression is

$(x + 5)/(x + 2) - \frac{(x + 1)}{ {x}^(2) + 2x}$

We factor the denominator of the second fraction to get,

$=(x + 5)/(x + 2) - ((x + 1))/( x( x+ 2))$

We can now see clearly that the LCM is

$x(x + 2)$

We collect LCM to get,

$=(x(x + 5) - (x + 1))/( x( x+ 2))$
We now expand the bracket to obtain,

$=\frac{ {x}^(2) + 5x - x - 1}{ {x}^(2) + 2x}$

This gives us,

$=\frac{ {x}^(2) + 4x - 1}{ {x}^(2) + 2x}$

The difference will be given by:
(x +5)/ (x +2) - (x + 1)/(x ^2 + 2x)
=(x +5)/ (x +2) - (x + 1)/[x (x + 2)]
the LCM is x(x+2)
thus the difference will be:
[x(x+5)-(x+1)]/(x (x + 2))
=[x^2+5x-x-1]/[x(x+2)]
=(x^2-4x-1)/[x(x+2)]

Answer:(x^2-4x-1)/[x(x+2)]

Answer:

R" has coordinates (-4,6)

Explanation:

The pre-image is the original, while the image is the altered form. The image is notated by a '. When you alter the image ('), you get ".

T is dilated (multiplied) by 5, so it goes from T = (1,-2) to T' = (5, -10)

R = (-2, 3) → (multiply by 5) → R' = (-10, 15) → (multiply by 2/5 or 0.4) → R" = (-4, 6)

Patients come into a medical clinic have a mean weight of 207.6 pounds with a standard deviation of 22.6 pounds. the distribution of weight is not assumed to be symmetric. between what two ways does Chebyshev's Theorem guarantee that we will find at least 95% of the patients? Round your answers to the nearest 10th

Answers

I know the answer it is 98.2

Answer: 105.9 lbs and 309.3 lbs

Step-by-step explanation:

By Chebyshev's Theorem, the proportion of patients with weights within 4.5 standard deviations of the mean is at least 95%. Therefore k=4.5.

The weight that is 4.5 standard deviations less than the mean is 207.6−4.5(22.6)=105.9 pounds.

The weight that is 4.5 standard deviations greater than the mean is 207.6+4.5(22.6)=309.3 pounds.

So at least 95% of the patients have weights between 105.9 and 309.3 pounds.
