Consider a finite population with five elements labeled a, b,c, d, and e. ten possible simple random samples of size 2 can be selected.
a. list the 10 samples beginning with ab, ac, and so on.
b. using simple random sampling, what is the probability that each sample of size 2 is selected?
c. assume random number 1 corresponds to a, random number 2 corresponds to b, and so on. list the simple random sample of size 2 that will be selected by using the random digits 8 0 5 7 5 3 2.

The ksp expression for the system pbcl2(s) pb+2(aq) + 2 cl-(aq) is: [pbc12][pb+2][2cl-] [pb+2][cl-]2 [pb+2][2cl-]2 [pbcl2][pb+2][cl-]2 [pb+2][2cl-]2[pbcl2]

Needmax recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
