Consider a population consisting of the values 3, 6, 5, 6, 4 and 3. what is the population mean?
If the population standard deviation is 4.2, what is the standard deviation of the sampling of the distribution of its means if the sampling distribution was derived with sample size n=4 and all possible samples were drawn with replacements?
What is the mean of the population if the mean of the sampling distribution of the means is 7.16?
What is the mean of the sampling distribution of its means if a population has means of 7.2?
create a class called person
populate the class with below private fields
1.First name as an String
2.Last name as an String

4.Dateofbirth as DateTime
Add a constructor that accept Firstname,Lastname,Email,DateBirth as Parameter
Add read only properties that return the following computer information
1.Isadult a bool- Whether or not the person is over 18
2.Sunsing as string - the traditional western sun sign of the person
3.Isbirthday as bool - wether or not today is the persons birthday
4 ScreenName as string - a default screeb name that you might seen being offered to a first time user of gmail or yahoo(e.g. hari joe born on may 25th,1980 might be hdoe525 or haridoe052580)

A piece of copper 700g is heated to100°c and then quickly transferred to a copper calorimeter of mass 20g containing 500g of liquid of unknown specific heat capacity of liquid calculate the specific heat capacity of copper 3900j/kg
A population consists of the numbers 1, 2, 3, and 4 with the sample size of 2. Compute the variance of the sampling distribution of means.
b. What weight of limestone should be taken so that 1/20 the number of milligrams of CaSO4 obtained will represent the percentage of CaO in the mineral?
You are designing a spherical tank, as shown in figure below, to hold water for a sonll village in
a developing country. The volume of liquid it can hold can be compuned as
V=pi*h2*
(3R-h)/3
where V is the volume of water in the tank in m3, b is the height of water in the tank in m, R is
the radius of tank in m. If R is 3m and V is 30 m.
Formulate the equation in terms of height (h), from above generalized equation, representing the
present situation
Use the correct built-in function in MATLAB to determine all possible values of height (h) that
will satisfy the formulated equation i.e. determine all possible roots of the formulated equation.
From those values height (h) which one is the correct and why?
What volume (in L) of 0.246 M HNO3 solution is required to react completely with 38.6 mL of 0.0515 M Ba(OH)2?Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O
