Question

The ___ for a procedure consists of all possible simple events or all outcomes that be cannot broken down any further. (A) rare event rule (B) probability distribution (C) random sample (D) sample space (E) experiment When using the always be careful to avoid double-counting outcomes. (A) addition rule (B) subtraction rule (C) multiplication rule (D) division rule (E) single rule A variable is a variable that has a single numerical value, determined by chance. for each outcome of a procedure. (A) parameter B) random relative (C) statistic (D) relative (E) unknown For the standard normal distribution a/an value is a z score separating unlikely values from those that are occur (A) uniform (B)rare (C) extreme (D) critical (E) unusual A continuous random variable has a distribution if its values are spread evenly over the range of possibilities. (A) Poisson (B) (C) normal (D) standard normal (E) uniform Finding probabilities associated with distributions that are standard normal distributions is equivalent to (A) finding the mean of the distribution. (B) finding the standard deviation of the distribution (C) finding the z-scores associated with the probabilities. (D) finding the variance of the distribution. (E) finding the area of the shaded region representing that probability. In the standard normal distribution, if you are asked to find the 97th percentile, you are being asked to find (A) an area corresponding to a z-score of -0.97. (B) a data value associated with an area of 0.97 lo its right. (C) an area corresponding to a z-score of0.97. (D) a data value associated with an area of 0.97 to its left. (E) a probability corresponding to an area of 0.97 to its left. As a procedure is repeated again and again, the relative frequency of an event tends to approach the actual probability. This is known as (A) the limit theorem (B) an impossible event (C) the law of large numbers (D) the rare event rule Two events A and B are if the occurrence of one does not affect the probability of the occurrence of the other. (A) dependent (B) mutually exclusive (C) disjoint (D) independent (E) not related

Explanation / Answer

1)answer - d

Sample space is the range of values or possible outcomes of a random variable or for a procedure

2)answer -a

When using addition rule always be careful to avoid double-counting outcomes.

3)answer - b

Random variable is a variable that has a single numerical value, determined by chance, for each outcome of a procedure.

4) answer - d

Critical value of Z seperates the unlikely values from the likely values that will occur

5) answer - E

uniform distribution is a symmetric probability distribution whereby a finite number of values are equally likely to be observed

6) answer - E
