Another variable Y follows a normal distribution with mean 25 and standard deviation
10. The maximum height of the density curve for X is_______ (i) the maximum height for the density curve for Y , and the area under the density curve for
X is__________ (ii) the area under the density curve for Y .

(A) (i) greater than, (ii) less than
(B) (i) less than, (ii) greater than
(C) (i) equal to, (ii) equal to
(D) (i) greater than, (ii) equal to
(E) (i) less than, (ii) less than

Answer 1

there is something missing from your question

Answer 2

no its the actual question

Answer 3

check that one

Answer 4

are u there?

Answer 5

you have to compair the standard deviations of each curve, remember that the sum of areas under each curve is one

Answer 6

but , how ? could you explain it?
