If I have an average 46.4% and the standard deviation is 2.2%. Does it agree with 43.97%? 46.4 % is experimental and 43.97% is theoretical.
Homework Answers
Experimental mean is the result of mean we have calculated with formula of mean having sum of all observations divided by number of observations.
Whereas theoretical means refers to mean we have finded by Central limit theorem and histogram of the data
The experimental mean and the theoretical mean both get same when we have a large n (the number of observations)
In your case both are having a difference, which seems to be unsatisfied and does not follow....

Write a program that computes the average and standard deviation of four scores. The standard deviation is defined to be the square root of the average of the four values. Use two functions. One function to calculate the average, this function should be with Return Type "double". Second Function should be to calculate standard deviation, this function should be with Return Type "void". Allow the program to continue until the user tells the program he/she is finished. This is for...

Men’s heights are normally distributed with a mean of 68.5 inches and standard deviation 2.2 inches. The U.S. Navy requires that fighter pilots have heights between 62 in. and 78 in. If the Navy changes the height requirements so that all men whose heights fall within the middle 82% of the population are eligible to be fighter pilots, what are the new requirements for men? Please show all your work and write your answer in a complete sentence. (7 points)
