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.

Step-by-step explanation:

dhhdhdhd is 0 c

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
