What are the 2 conditions that determine a probability distribution?
The value of the distribution for any value of the random variable must be in the range [0, 1]. The sum (or integral) of the probability distribution function over all possible values of the random variable must be 1.
What is the probability that a standard normal variable will be between the values of -2 and 1?
0.636 approx.
Is family size a continuous variable?
No, this is a discrete variable since it can assume only whole number values: 0, 1, 2, 3, ... . A continuous variable would be one such as volume of water in a swimming pool which could be measured in real number units of volume.
What would -2 standard deviation below the mean be?
It would mean that the result was 2 standard deviations above the mean. Depending on the distribution of the variable, it may be possible to attach a probability to this, or more extreme, observations.It would mean that the result was 2 standard deviations above the mean.

According to the normal probability distribution 95 percent of the values of a normal random variable are contained w in plus or minus how many standard deviations from the mean Why is that important?
Approximately 2 standard deviations (1.96, actually) from the mean. That is important to know that if one has a sample of 1000 values, if one selects a threshold at +/- 2 standard deviations from the mean, then one expects to see about 25 values exceeding those thresholds (on each side of the mean)
What data can have only 2 values?
A binary variable.

How do you complete a table of values with the equation -2y 6x-2?
Given a value for the variable x, you find (calculate) the corresponding value of y. These (x, y) pairs are part of the table. You cannot complete the table because there are infinitely many possible values of x.
What are the possible values of ml for an electron in a d orbital?
2,1,0,-1,-2 are the possible values of ml for an electron in d orbital.
A sentence with the word dependent variable?
"If y=2x, then x is the independent variable and y is the dependent variable." Also, " If x=y/2 then y is the independent variable and x is the dependent variable". Also, "The dependent variable is the one variable which is found by giving values to all the independent variables"
Are there any values of the variable A for which the expressions 2 plus A and 2A have the same value?
2. 2 plus 2 equals 4 and 2(2)= 4
Is a discrete variable normally described as a word?
No.A discrete variable is a variable that can not assume all possible values within a given range.For example, if I were to conduct a survey on the number of children people had, then my answers would be numbers such as 0, 1, 2 and so forth (i.e. they would be whole numbers). This particular variable could not have a value in between these (a non integer value), such as 1.345, as this makes no sense in this context. This makes the variable discrete.
When a number is a multiple of 2 what are the possible values for the ones digit?
The values are : All even numbers and zero.
Is the number of popcorn servings sold per day an example of a continuous variable?
The number of popcorn servings sold per day is actually an exemple of a discrete variable. A discrete variable can only take on certain values within its variable range (1, 2, 3, etc). As such, the number of servings can only take on those values, that are whole numbers, without decimals. You cannot say that you have 1.5 desks in your room, for example. You have 1, 2 or 3 desks. On the contrary, a continuous variable is one that, within its variable range, can take any value. Time would be a good example. Between 2 o'clock and 3 o'clock, there are other values. A student can say it took 2 hours and 10 minutes to complete his exam, for example.
How many possible values are there for the spin quantum number?
two --- + 1/2 or - 1/2
