What is your question? There is no data.

Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. (-5*-12)/-4 = 60/-4 = -15 A minus times/divided by a minus is a plus. A minus times/divided by a plus is a minus.

What organism? What stimulus? Flight or fight? Ignore? Approach?

If not E, I would pick C for the same reason.

I would pick E. Out of 100 factors, P = .03 is the probability that 3 would have statistical significance.

Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.

Rupees * residents = 202500 √202500 = ?

Statistics
Biased. First of all, are you dealing with bachelors, masters or doctorate levels? Second, they probably do not represent the total population of degree graduates, but only those in your institution, which may or may not be a good representation of the population.

statistics (?)
Have you followed the "steps in Problems 1 through 4"?

Math- combinations
You can get ten (10) different numbers in each space. If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

Maths (?)
The minimum of what?

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 score.

What they care about most is money, stock prices and problems concerning finance. They may never notice that there are lots of social problems(COMMA) which actually need their concern. Make sure that it is clear who the "they" are.

Relative dispersion, sometimes called the coefficient of variation, is the result of dividing the st. dev. by the mean, hence it is dimensionless (it may also be presented as a percentage). So a low value of relative dispersion usually implies that the st. dev. is small in com...

It is a short cut to using words.

Nope. Have you looked up each of these in your text or Googled them? In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

Stats
F is definitely true, since it essentially repeats your data. The rest depend on what critical value you are using to reject the null hypothesis. The most commonly used are P≤.05 or P≤.01.

adolescents and other problems
"a high drive level" is internal rather than being caused by learning from others. Does that help you to choose the right answer?

adolescents and other problems
A gets my vote too.

adolescents and other problems
Nope, B.

children growing up
Although you need the basic biological abilities for speech, it is triggered by social interaction.

What was the quotation?

child psychology in general
Yes, we are all biased by our past experiences.

English
Rather than repeating it, just extend the "ou" sound of the "o".

adolescents and other problems
Right.

adolescents and other problems
Right.

adolescents and other problems
I could see either the motivation (attracted or repelled) or the outcome (rewarding, punishing or neutral) being plus or minus.

adolescents and other problems
Don't agree. A stimulus is either there or not, rather than minus.

adolescents and other problems
Now you have it.

adolescents and other problems
I don't agree. what specific mental abilities would they measure?

adolescents and other problems
Right.

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events. a. Without replacement: 6/8 * 5/7 * 4/6 = ? b. You want probability of one or both being chosen. Either-or probabilities are fou...

Physiology
What do you think? It is asking for your thoughts, not ours.

math
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events. P(1) = .85 * .15 = ? P(2) = .85 * .85 = ? Either-or probabilities are found by adding the individual probabilities.

math
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events. Assuming that the numbers cannot be repeated, 6/49 * 5/48 * 4/47 * 3/46 * 2/ 45 * 1/44 = ?

math!
3 = 1,2 or 2,1 = 2/36 7 = 6,1 or 1,6 or 5,2 or 2,5 or 3,4 or 4,3 = ? Either-or probabilities are found by adding the individual probabilities.

math
P(12) = 15/(5+8+15+2) = ?

math (incomplete)
It would help if you proofread your questions before you posted them. How many were solid at "150 each"? How can only "758 were collected," when just "258 adult tickets at 255 each" = 65,790?

It would be clearer if you spelled out the other alternatives beside standard deviation.

Math Statistics
It seems like you do not have a normal distribution, since the confidence interval goes from .003 below to .013 above .50. The confidence interval is determined by the standard error of the mean (SEm). SEm = SD/√n From your data, you would have an extreme large n. Howeve...

It is the relationship of x to y with z factored out.
