What is the 95% CI for data set 2?
vesna_86 [32]

Answer: 20 ± 11.32

Explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values where there is a % certainty the true mean value lies in. For example, a 95% CI means there is a 95% certainty the true mean value lies in the interval.

For the data set 2, z-value for 95% confidence interval is z = 1.96

Formula to calculate CI is

x ± z\frac{s}{\sqrt{n} }

where

x is mean

z is z-value

s is standard deviation

n is the sample number

Then:

20 ± 1.96\frac{10}{\sqrt{3} }

20 ± 1.96\frac{10}{1.7320}

20 ± \frac{19.6}{1.7320}

20 ± 11.32

The 95% CI is 20 ± 11.32, which means there is a 95% certainty the true value is between 8.68 and 31.32.

Read each description below and determine whether or not it describes a function or property of cerebrospinal fluid. Identify wh
Ostrovityanka [42]

Answer:

Produced by the choroid plexus -T.This is the major secretion site.It is also produced in smaller quantities in the interstitial compartment.

Blocks blood toxins from brain tissue-F, that is the job of  the blood brain barrier(BBB).

Supplies oxygen to the brain tissue-T.This gas is dissolved  in the CSF together with CO2 for distribution among nervous tissues by the CSF

Maintains the concentration of glycine surrounding the brain-T

Found in the ventricles of the heart and brain-False,it does not reach the heart ventricles.This are occupied by blood.

Prevents concussions-T

Produces antibodies in response to antigen exposure in the brain tissue-False.These are produced by the B-cells, not by in the CSF,based on the  specif antigen stimulation.

Effectively decreases the brain's weight-T It reduces the weight of the brain.This is done by the buoyancy it provided for the brain.

Compared to levels in the blood plasma, the CSF is higher in glucose-F.This is wrong, the glucose of the blood plasma is higher.But equal sodium ion,more chloride in CSF, and less protein.It s levels is a relefection of blood glucose.Although it may lag 2-4hrs in the CSF.

It prevents concussion,(T)and and the contraction of cardiac muscles propels its movement(T).
