Question

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.

Answer 1

Can you help with this?

Answer 2

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

Answer 3

okay

Answer 4

im thinking its gonna be a \(H_o=\) and \(H_a\ne\) type of format

i dont spose there are options to choose from?

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

\[H_1:P(chute~opens)\]
\[H_o:P(chute~doesnt~opens)\]

...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

Answer 11

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

Answer 12

it's okay I understand your pain

Answer 13

but I am going with the consequences as well
