For random samples of size 100 from a population, the mean of the sample means from all possible samples is <u>less than</u> the population means.
The suggestion of the pattern means will equal the population suggest. the standard deviation of the distribution of the sample means, called the same old blunders of the suggested, is the same as the population trendy deviation divided by means of the rectangular root of the sample length (n).
The general sample suggests components for calculating the pattern mean.
The populace suggest is the mean or average of all values within the given population and is calculated by using the sum of all values within the population denoted with the aid of the summation of X divided by way of the number of values in the population that's denoted with the aid of N.

Answer:

Step-by-step explanation:
The options to get 2 of different color is picking blue then red or red then blue.
Starting with picking blue then red.
The chance to pull blue first is 3/7. Then since the marble is replaced the chance to pull red next is 4/7.
The chance to get those in that specific order is the product of the two fractions. (3/7) * (4/7) = 12 / 49
The second option of getting red then blue will be the same as above but 4/7 then 3/7 with the same result of 12/49.
To finish, add the two probabilities together 12/49 + 12/49 = 24/49.
Explanation:
To find if 0 is greater than -1 we can graph these values on a number line. If 0 is to the left of -1 then is less than -1, if it's to the right, then it's greater than -1:
Answer:
Yes, 0 is greater than -1.
