Consider a population consisting of 2, 4, 6, 8 and 10. Suppose samples of size 3 are drawn from this population.
a. Describe the sampling distribution of the sample means
b. What are the mean and variance of the sampling distribution of the sample means? c. Construct a histogram for the sampling distribution.

Consider a population consisting of 2, 4, 6, 8 and 10. Suppose samples of size 3 are drawn from this population.
a. Describe the sampling distribution of the sample means.
b. What are the mean and variance of the sampling distribution of the sample means?
c. Construct a histogram for the sampling distribution,
x= 0, 1, 2, 3, 4, 5
p(x)= 0.1,0.3,0.4,0.1,?,0.5
find p(4)
construct probability histogram to describe p(x)
Calculate the molar concentration of each of the following:
a. 6.0 N sulfuric acid (in reactions that replace both hydrogens)
b. 3.5 N potassium hydroxide
c. 4.0 N phosphoric acid (in reactions that replace two hydrogen ions)
d. 6.2 N sodium hydroxide
Calculate the percent concentration of each of the following solutions:
a. 2.50 N sodium hydroxide solution (density = 1.25 g/)
b. 4.80 N potassium hydroxide solution (density= 1.30 g/ m/)
Make a program that will accept an integer and loop for the same number of times as that of the inputted integer and input random integers and add it to the array/list one by one, per line. Afterwards, make your program accept another random integer.
Using that final integer, compare from your array/list if the final integer's value is also present in your current array/list. If so, print "Present"; otherwise, print "None".
Start coding now!
Input
The first line contains the size of the array.
The next lines contain the integers.
The last line contains an integer to be searched.
