The probability you reject the null hypothesis when in fact the null hypothesis is true is called А) а Туре I еrror а Туре II error B) C) the power

9)   A hypothesis test is to be conducted using the claim that the mean hourly wage of employess in a large company is at least $21. What are the null and alternative hypothesis? pick one    a H 0 :    21   vs  H a :   < 21   b H 0 :  μ ≤ 21   vs   H a :  μ > 21   c H 0 :  μ  21   vs  H a :  μ < 21   d H 0 :  p  21   vs   H a :  p < 2

Please answe this problem, Inference rule. Show your solution. thank you

Background: A dog named Zip is often tied to a zipline. Fig 1A: Top view of yard. When tied, Zip travels in such a way that the hook on the line slides back and forth as he moves. A coordinate system is defined as described in the picture to the right. Figure 1A shows a top view and Figure 1B shows a Fig 1B: Sideview of zipline. sideview. A measurement system is connected to the hook. It periodically records the position on the line during the time Zip is connected to it. After 50,000 x=0 location of hook observations (electronically recorded) a continuous model for where the hook is located was developed by - 10m < x < 10m a team of engineers. They came up with the model that p(x) = {A + 10) otherwise 1) Sketch a graph for p(x). Do you need to fill in this form? You can use Fill & Sign to complete form yourself or get others to sign. 2) What is the average position of the hook on the zipline?
