Apopulation has a mean of 200 and a standard deviation of 50. suppose a sample of size 100 is selected. what is the probability that the sample mean will be within latex: \pm±10 of the population mean?

0.9544

Step-by-step explanation:

As per given have ,

Population mean :

Standard deviation :

Sample size : n= 100

We assume that the population is normally distributed.

Let be the sample mean.

Now , the probability that the sample mean will be within ±10 of the population mean will be :-

Hence, the required probability is 0.9544.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
