If a bag contains 4 red marbles, 7 green marbles, 9 yellow marbles, and 2 black marbles. If you randomly draw a marble from the

Soloha48 [4]

I think that it would be B). 1/2

The reason I think that is because if you add all the marbles up you get 22. Then if you add the red and the green marbles you get 11. 11 is half of 22 making it a 50% chance. 1/2 is the same as 50% or a half.

A high school statistics class wants to estimate the average number of chocolate chips in a generic brand of chocolate chip cook

Viktor [21]

Answer:

Correct option:

We are 95% certain that the confidence interval of 18.6 to 21.3 includes the true average number of chocolate chips per cookie.

Step-by-step explanation:

The general formula for the (1 - α)% confidence interval for population mean is:

$CI=\bar x\pm CV \times SE_{\bar x}$

Here:

$\bar x$ = sample mean

CV = critical value

$SE_{\bar x}$ = standard error of mean.

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

The 95% confidence interval for the mean number of chocolate chips per cookie is (18.6, 21.3).

This 95% confidence interval implies that there is a 0.95 probability that the true mean number of chocolate chips per cookie is between 18.6 and 21.3.

Thus, the correct option is:

"We are 95% certain that the confidence interval of 18.6 to 21.3 includes the true average number of chocolate chips per cookie. "
