Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 77.577.5 mbps. the complete list of 50 data speeds has a mean of x overbarxequals=17.1517.15 mbps and a standard deviation of sequals=35.8835.88 mbps.
a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds?
b. how many standard deviations is that [the difference found in part (a)]?
c. convert the carrier's highest data speed to a z score.
d. if we consider data speeds that convert to z scores between minus−2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant?

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

answer: options

step-by-step explanation:

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.
