Arithmatic Mean

They are effectively the same but the standard deviation is more popular because the units of measurement are the same as those for the variable.

The standard deviation is better since it takes account of all the information in the data set. However, the range is quick and easy to compute.

Because probability can't be greater than 1.

Yes, but that begs the question: how large should the sample size be?

Yes, if you mean normal with a mean other than 0 and/or standard error other than 1.

If m is the mean and s the standard error, then transform the original data, y, using:

z = (y - m)/s

z will have the N(0,1) distribution!!!!!!!

The probability is 6/52 = 3/26.

From a 52 card deck, probability is 1/52.

The probability is 0.0322

The probability of a club is 1/4 and the probability of a diamond is 1/4 so since they are mutually exclusive you just add them and the total probability is 1/2

Of course there are 4 suits, and clubs and diamonds are 2 of the 4 so we could have just said 1/2.

There are three odd numbers in a die: 1, 3, 5.

The probability of rolling an odd number in a fair die is: P(1 or 3 or 5) = 3/6 = 1/2

good

There are 7!/4! = 210

2.27%

50/50

well a sample size can be any size depending on the requirements. A sample size could be 10 people of that entire population or it could be 1000 people.

Yes it is possible.

It is y = 0
