Answer:
The z-statistic lies in the critical region
Step-by-step explanation:
When a hypothesis test is performed, the decision to reject or not reject the null hypothesis is made on basis of following observations:
- If the z-statistic falls in the critical or rejection region, there is enough evidence to reject the Null Hypothesis
- If the z-statistic falls outside the critical or rejection region, there is not enough evidence to reject the Null Hypothesis.
In the given statement Zachary rejects the Null Hypothesis, this means the z-statistic she calculated must have been inside the critical or rejection region. Hence the correct answer would be:
The z-statistic lies in the critical region
Answer: At x= 25 there is a break even point .
Step-by-step explanation:
Let the number of CDs be x
For the case of iTunes,
Cost of each CD = $12
For the case of Best Buy,
Number of CDs of free of cost = 5
Number of CDs more than 5 = $15
We need to find the "Break even point ":
According to question,

Hence, At x= 25 there is a break even point .
I think answer should be 8 please give me brainlest let me know if it’s correct or not okay thanks bye I appreciate it thanks
Apply the exponent rule x^a /x^b = x ^(a-b)
10^15 / 10^5 = 10^(15-5) = 10^10
