Arandom sample of size 25 is taken from a nor- mal population having a mean of 80 and a standard deviation of 5. a second random sample of size 36 is taken from a different normal population having a mean of 75 and a standard deviation of 3. find the probability that the sample mean computed from the 25 measurements will exceed the sample mean com- puted from the 36 measurements by at least 3.4 but less than 5.9. assume the difference of the means to be measured to the nearest tenth.

2nd one in the first row is correct

hi how are you doing today, if you need just ask me.

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
