Probability

There is no such thing as "the usual sampling distribution". Different distributions of the original random variables will give different distributions for the difference between their means.

5/5

It is 2/13.

In this economy, no job is easy to get. However, PE teachers do not require too much prior knowledge, so the odds compared to other teaching jobs are very good.

When you assess the situation, you review the problem and look over possible outcomes for the situation.

At-home kits that use saliva instead of urine to help determine ovulation have made it more convenient for women trying to conceive children to track their hormonal cycles, eliminating a lot of guesswork.

It is 13/51.

In 34 or fewer tosses, the answer is 0. In infinitely many tosses, the answer is 1. The answer depends on the number of tosses and, since you have chosen not to share that critical bit of information, i is not possible to give a more useful answer.

For two fair die, it is 5/36.

cm zC

In two successive rolls, it is 1/6 otherwise it is a near certainty.

No, the mint has two dies to stamp the coins. One die for heads ond for tails. They fit into different parts of the machine. If you have a two headed coin you have a novelty coin. While there are no known 2-headed U.S. coins, there are 4 certified examples of genuine 2-tailed U.S. coins. And there are about 25 known genuine 2-headed or 2-tailed coins from other countries. Details about this can be seen here : http://varietynickels.com/articles/twotailed.htm The U.S. Mint designs their dies with different slots in the heads-side dies than those in the tails-side dies to prevent this error from happening. So you can see the likelihood of you having a genuine 2-headed or 2-tailed coin is infinitely small -- even less than your chances of winning the lottery. Most coins with two heads were struck at a mint the regular way, but they were cut in half and the two heads were put together by a skilled craftsman.

The two events are independent, so the answer is simply the multiple of the probabilities of the two events. So joint prob = 1/6 * 1/2 = 1/12

yes

there is no pdf in hottling t sq test there is only mdf or it has multivariate distribution function

The answer depends on how many cards are drawn, whether or not at random, from ordinary decks of cards, with or without replacement.

Since a cube has 6 sides, you have a 4 in 6 chance of getting a number less than 5 each time you roll the dice. You would take how many times you want to roll it (360), divide it by the number of sides (6), and multiply it by 4 since you know you have a 4 in 6 chance. So it should be 240. This is strictly mathematical though and you should not consider it accurate since there are many variables when rolling it.

i think it give equal chance for all.

Risk Level

The answer depends very much on where in the world the employee is.

you should state your opinoin

Conflict Antecedent

Assuming the numbers on the cube are 1, 2, 3, 4, 5, and 6, 100% or 1. However, the question doesn't specify the numbers on the cube, so it technically could have 20, 21, 22, 23, 24, 25 written on it. The answer you are probably looking for is the first one, though a more rigorous answer would be "not enough information, the numbers on the cube aren't given".

Standard deviation is a measure of how spread out a set of numbers are from each other. It has a variety of uses in statistics.
