Answer: $220

Step-by-step explanation:

Formula to find Average :

\text{Average}=\dfrac{\text{Sum of all observations}}{\text{Total number observations}}

Let x be the  amount she must sell in the sixth year in order to qualify.

Given : In an annual sales contest, Lisa sold $188, $212, $214, $196, and $200 worth of products in the first five years.

Then, the average over six years would be

\text{Average}=\dfrac{188+212+214+196+200+x}{6}

In order to qualify for the grand prize, she must average at least $205 over six years.

i.e. \text{Average}=\dfrac{188+212+214+196+200+x}{6}\geq205

\Rightarrow\ \dfrac{1010+x}{6}\geq205

\Rightarrow\ 1010+x\geq205\times6

\Rightarrow\ 1010+x\geq1230

\Rightarrow\ x\geq1230-1010

\Rightarrow\ x\geq220

Hence, the least amount she must sell in the sixth year in order to qualify= $220

NeX [460]

Answer:

Part 1

Type II error

Part 2

No ; is not ; true

Step-by-step explanation:

Data provided in the question

Mean = 100

The Random sample is taken = 43 students

Based on the given information, the conclusion is as follows

Part 1

Since it is mentioned that the classes are successful which is same treated as a null rejection and at the same time it also accepts the alternate hypothesis

Based on this, it is a failure to deny or reject the false null that represents type II error

Part 2

And if the classes are not successful so we can make successful by making type I error and at the same time type II error is not possible

Therefore no type II error is not possible and when the null hypothesis is true the classes are not successful
