The financial aid office of a university asks a sample of students about their employment and earnings. The report says, "For academic year earnings, a significant difference (P = 0.028) was found between the sexes, with men earning more on the average."
True or false:
The report shows that the difference in earnings in the sample was large enough that it would occur in less than 3 percent of samples drawn from a population in which men's and women's average earnings are equal.

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

answer is b.
