The answer would be: White blood cell (WBC) count of 20,000/mm3
Peritoneal dialysis is an invasive treatment that involves an injection of fluid to the peritoneal space. It has a high risk of infection, which could cause peritonitis. Increases of white blood cells is a sign of infection. Peritoneal dialysis needs to be stopped if the infection occurs.

klasskru [66]

Answer:

The lake was the result of an ice dam on the Clark Fork caused by the southern encroachment of a finger of the Cordilleran Ice Sheet into the Idaho Panhandle. It was the largest ice-dammed lake known to have occurred.

Humerus bones from the same species of animal have approximately the same length-to-width ratios. It is known that Species A has

Dima020 [189]

Answer:

The unearthed Humerous bones don't belong to the species A.

Explanation:

Hello!

You are studying the Humerus bones species A, who is known to have a mean ratio of 8,5. This value corresponds to the population mean of the length-to-with ratio of bones of species A, symbolized as μ.

The hypothesis you want to study is "The Humorous bones unearthed belong to the species A" if you assume this to be true, then the mean of the length-to-with ratio should be equal to the known population mean of the length-to-with ratio.

Symbolized:

H₀: μ = 8,5

H₁: μ ≠ 8,5

Significance level: α: 0,05

You are asked to use a Z-test, since you don't know the value of the population variance, but have the sample values, the sample size is big enough (more than n=30). Assuming that the sample values are independent, the statistic test of choice is the approximation:

$Z= \frac{x_bar-μ}{S\sqrt[]{n} }$ ≅N(0;1)

The critical region, in this case, it's a two-tailed test (remember the type is determined by the null hypothesis) so you'll have two critical values.

Left value [/tex] $Z_{\alpha/2} = Z_{0,025} = -1,96$

Right value $Z_{1-\alpha/2} = Z_{0,975} = 1,96So you'll reject the null hyphotesis if the calculated [tex]Z_{obs}$ value is ≤-1,96 or ≥1,96 and you'll support it if -1,96< $Z_{obs}$ <1,96

Now we calculate the statistic by replacing the formula with the data:

x_bar = 9,26

S = 1,20

n = 41

$Z_{obs}= \frac{x_bar-μ}{S\sqrt[]{n} }$

$Z_{obs}= \frac{9,26-8,5}{1,20\sqrt[]{41} }$

$Z_{obs}$ = 4,0553

Since the calculated value falls in the rejection region, this means, you have statistically significant results. In other words you can reject the null hipothesis (H₀: μ = 8,5) and asume that the unearthed Humerous bones don't belong to the species A.

I hope you have a SUPER day!
