**Statistics**

When you have specific data, it is descriptive. When you go outside the actual data, it is inferential. 1. a, b and c infer. 2. a describes, b and c infer.

**Math Statistics**

Z = (score-mean)/SD Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportions/probabilities related to the Z scores. Reverse process with last question, starting with .90.

**science**

coitus, genes, traits?

**science**

Was the girl cloned? Otherwise it is not exact.

**maths**

100 cm = 1 m 60/100 = ?

**statistics**

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability ([1-.87]/2) and its Z score. 87% = mean ± Z(SD) Fill in the values and calculate.

**statistics**

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability ([1-.99]/2) and its Z score. 99% = mean ± Z(SEm) SEm = SD/√n

**Math**

Area = 1/2 height*base Assuming that the above are height and base, 170 * 800 = 136,00 sq. feet 1 acre - 43,560 sq. feet 136,000/43,560 = ?

Excuse me. Is .05 > P > .01? Again, we don’t know.

I don’t know how you define “1 block.” Jane’s amount factors into 15 * 5, therefore Peter would factor to 15 * 2 = 30. Is that what you mean by “1 block”?

Each person received 7/4 pounds. 2(7/4) were given to food pantry. It would help if you proofread your questions before you posted them. You seem to be missing a unit designation for the apple sauce. 1 2/3 what?

What Human Relations function did you choose?

Find the mean first = sum of scores/number of scores. Range = highest score - lowest score. Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance. Standard deviation = square roo...

As the distance increases, the gravitational forces between the two objects decreases. It is an inverse relationship. This means the statement is true.

Steve seems to be ignoring that you might pick 4 socks of the same color in a row.

**Math**

First the choice of one color = 4/8. With the 7 remaining socks, the choice of the other color = 4/7. With 3 remaining of each color in the 6 socks left, P = 3/6. If the events are independent, the probability of both/all events occurring is determined by multiplying the proba...

From your set of numbers, there is no mode or modal class. If the scores were grouped into intervals, one could be the modal class. The mean or median would be better to indicate average class sizes. Any of the measures of central tendency can be used, if the distribution is r...

Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. 81 * 38 = 3078, which is the product. For 81, 3 * 3 * 3 * 3 are factors. However, 81 and 38 are also factors of 3078.

From your data, with four tosses, you would get 3 tails and one head by chance. The probability of one head would then be 1/4. If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
