I 'm not sure but the answer might be A.
Answer & Explanation:
The null hypothesis (H0) is what the study is trying to reject, is what the study wants to disprove. In this case, the financial administrator believes that the average cost of tuition and room is greater than $8,500. Then, he wants to statistically disprove that the average cost per term is equal to $8,500.
H0: average cost = $8,500
H0:μ=$8,500
The alternative hypothesis (H1) is the opposite, is what the financial administrator wants to prove: the average cost per term is greater than $8,500.
H1: average cost > $8,500
H1:μ>$8,500
The number of subscribers that Tyler loses each month is referred to as churn.
The churn drill is a large drilling machine that bores huge diameter holes in the ground. In mining, they were used to drill into the gentle carbonate rocks of lead and zinc-hosted regions to extract bulk samples of the ore. Churn drills are also referred to as percussion drills as they function by lifting and losing a heavy chisel-like bit which breaks the rock as it falls. Churn drills are handiest in smooth- to medium-density rock of incredibly shallow intensity
Churn drills had been invented as early as 221 BC in Qin dynasty China,[1] capable of accomplishing an intensity of 1500 m. Churn drills in ancient China were built of wood and exertion-intensive but had been able to go through strong rock.
