A group of high-risk automobile drivers (with three moving violations in one year) are required, according to random assignment, either to attend a traf?c school or to perform supervised volunteer work. During the sub-sequent ?ve-year period, these same drivers were cited for the following number of moving violations:

NUMBER OF MOVING VIOLATIONS TRAFFIC SCHOOL VOLUNTEER WORK 26 15 14 23 10

(a) Why might the Mann-Whitney U test be preferred to the t test for these data?
(b) Use U to test the null hypothesis at the .05 level of signi?cance.
(c) Specify the approximate p -value for this test result.

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.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
