There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors
zhuklara [117]
<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3),   (1,4),   (1,5),   (1,6)

(2,3),  (2,4),  (2,5),  (2,6)

(3,3),  (3,4),   (3,5),  (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.

hoose the correct definition of a sampling distribution. The sampling distribution of a statistic of size n n is the distributio
sergey [27]

Answer:

Correct option:

"The distribution of the statistic in all possible samples of size <em>n</em> from a given population."

Step-by-step explanation:

The sampling distribution is a probability distribution of a sample statistic.

A sample statistic is a numerical value representing a characteristic of a sample. For example, the sample mean represents the mean value of the sample, the sample variance represent the variance of the sample. Both of these values are sample statistic.

A statistic is an unbiased estimator of the parameter value.

That is, the sample mean value can be used to estimate the value of population mean.

If various large samples are taken from a population and the sample statistic value is computed for each of these samples, then the probability distribution of theses sample statistic is known as the sampling distribution.

The mean of the sampling distribution is same as the population mean and the standard deviation of the sampling distribution is known as the standard error.

The correct option is:

"The distribution of the statistic in all possible samples of size <em>n</em> from a given population."
