12/2 , because 12 divided by 2 is 6
The probability would be 2/11 because there are two markers that are purple and gray. Also, there are 11 markers. So my final answer is 2/11.
If you add the two terms on the right, you will get 5^14. 14 is your answer.

Answer: D
H0: μ=522
H1: μ>522
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
So, for this case;
The null hypothesis is that the mean score equals to 522
H0: μ=522
The alternative hypothesis is that the mean score is greater than 522.
H1: μ>522
