Answer:

D.

Step-by-step explanation:

we see a1 = 6.

that is the starting value. everything else then (to generate the new sequence elements) is added to this.

so, B and C are out.

and clearly, for every new sequence element we add -3. and we do this for every sequence element except for a1. so we add -3 (n-1) times.

therefore, only D is correct.

In order for an airline to cancel a flight, there needs to be over 6 inches of snow on the ground. Suppose we want to do a test
Lunna [17]

Answer:

Step-by-step explanation:

From the given question.

We can write the null hypothesis & the alternative hypothesis as:

Null hypothesis:

\mathbf{H_o: \mu \leq 6}

Alternative hypothesis:

\mathbf{H_{a}:\mu >6}

From above, let's think about the type I error we could make and the type II error we could make.

<u>Type I error:</u>

The type I error at the null hypothesis showcases that the snow level is at 6 inches or below 6 inches, but we falsely concluded that the snow level is high above sea level.

<u>Type II error:</u>

Here, the snow level is literally above 6 inches, hence, we failed to conclude that the snow level is above 6 inches.

Thus, the consequences of the above analysis showcase that type II error has higher severe consequences because it may result in a situation that may endanger the passengers' safety.

Why would a statistician consider an inference incomplete without an accompanying measure of its​ reliability?
beks73 [17]

Answer:

An inference without a measure of reliability is nothing but a guess. The measure of reliability separates the science of statistics from the art of story telling. It gives a statistician a level of confidence that an inference made can to a reasonable extent be trusted
