## DarkendSinz30 2 years ago When a parachute is inspected, the inspector is looking for anything that might indicate the parachute might not open. - State the null and alternative hypotheses for this situation.

1. DarkendSinz30

Can you help with this?

2. amistre64

maybe, its been awhile since i had to fight with this :)

3. DarkendSinz30

okay

4. amistre64

im thinking its gonna be a \(H_o=\) and \(H_a\ne\) type of format i dont spose there are options to choose from?

5. DarkendSinz30

no but i am thinking from an example in my text book it goes from Ho and H1 that the parachute will open or the parachute will not open

6. DarkendSinz30

so with that being said those were the choices that were offered

7. amistre64

that does seem appropriate h1 is what we want to happen; h1 = parachute opens h0 is the opposite of that, the null, h0 = parachute doesnt open

8. DarkendSinz30

right but it is asking for the null and alternative so we have two types of errors that could happen right?

9. DarkendSinz30

A Type I Error occurs if we conclude the parachute will not open when in fact, it will. Consequences: The parachute will be rejected, and a new one put in its place. Money will be spend needlessly, and a perfectly good parachute will be wasted

\[H_1:P(chute~opens)\] \[H_o:P(chute~doesnt~opens)\] ...oy vey, yes there are errors that can creep in; it is true, but we say its false; its false, but we say its true

cant say i was ever good with mixing english with math :)

12. DarkendSinz30

it's okay I understand your pain

13. DarkendSinz30

but I am going with the consequences as well
