Given this list of students containing age and name, students = [{"age": 19, "name": "Eunice"}, {"age": 21, "name": "Agnes"}, {"age": 18, "name": "Teresa"}, {"age": 22, "name": "Asha"}], write a function that greets each student and tells them the year they were born. e.g Hello Eunice, you were born in the year 2002.
Create a Class Rectangle with the following Attributes and Methods
Attributes: The class has attributes width and length that represent the two sides of a rectangle
Methods:
Add a method named area which returns the area (A) of the rectangle using the formula A=width*length
Add a method named perimeter which returns the perimeter (P) of the rectangle using the formula P=2(length+width)
Consider a population consisting of 3, 6, 7, 9, 10, 4, and 8. Suppose samples of size 2 are drawn from this population. Describe the sampling distribution of sample means. What is the standard deviation of the sampling distribution? NOTE: EXPRESS YOUR ANSWER INTO 4 DECIMAL PLACE VALUES
The decomposition of PCl5 is shown below:
PCl5(g)⇌ PCl3(g) + Cl2(g) Kc = 0.029 at 85°C
Find out if the reaction proceeds forward, backward, or if the system is at equilibrium when a 1 liter
container is filled with 0.4 mole PCl5, 0.5 mole PCl3, and 0.2 mole Cl2.
Aqueous iron (III) chloride and sodium carbonate solution yields aqueous sodium chloride and a precipitate of iron (III) carbonate.
It is known that cellular phones batteries by a certain factory have lifetimes that follow a normal distribution. The average lifetime of the batteries is known to be 2.4 years. A random sample size of 16 will be taken.
1. Determine the mean and the standard error of the sampling distribution of the means.
2. What is the distribution of the sampling distribution of the sample mean?
3. What is the probability that a random sample size of 16 will have a sample mean greater than 2.5 years?
4. What is the probability that a random sample of size 16 will have a sample mean of less than 2.2 years?
Given the population: 1, 3, 4, 6, and 8; and suppose samples of size 3 are drawn from this population:

2. How many different samples of size n=3 can be drawn from the population? List them with their corresponding means
3. Construct the sampling distribution of the sample means.
4. What is the mean of the sampling distribution of the sample means?
5. What is the standard deviation of the sampling distribution of the sample means?
