A researcher is studying psychological factors in academic achievement among teenage girls. One variable she is particularly interested in is competitiveness. What information does a measure of variability for the variable competitiveness convey? Check all that apply. Do all teenage girls have the same amount of competitiveness? What is the average value for the variable competitiveness among teenage girls? How consistent are the values for competitiveness among teenage girls? What is the most common value for the variable competitiveness among teenage girls?

The correct answer is:option A and B

Step-by-step explanation:

A researcher is studying and examining psychological factors in academic achievement amongst teenage boys. One of the variable he is particularly paying more attention is in determination.

The quantifying of variability for the variable determination suggests how stretched out are the values for determination amid teenage boys (do all boys that are still in their teenage years have the same determination) and how constant are the values of determination amid teenage boys.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
