Question
1. The area of an event in the sample space is equal to its probability.
true or false
2. What characteristics do the "best" estimates of population parameters have? (choose all that apply)
a.the statistic obtained from any single sample of the population will be very close to the value of the parameter being estimated
b.when a large number of samples from the population is taken, the outllying samples will balance each other out
c.even if the sample size increases the value of the statistic being measured will not vary greatly
a.the statistic obtained from any single sample of the population will be very close to the value of the parameter being estimated
b.when a large number of samples from the population is taken, the outllying samples will balance each other out
c.even if the sample size increases the value of the statistic being measured will not vary greatly
Explanation / Answer
Result:
1. The area of an event in the sample space is equal to its probability.
true
To find the probability of any event associated with a random experiment we divide the number of outcomes of that event with the total number of possible outcomes of the whole experiment that is the sample space.
