Hypothesis Testing

[wet oasis]

Shouldn't the alternative hypothesis be p > 0.3 because the teacher is claiming that they are using more gold beads during the activity

in this example shown it says the researcher thinks the candidate is overestimating meaning they think the candidate would have less than 40 percent support

[wet oasis]

so in the context of this question if the teacher thinks they used more golden beads during the activity then shouldn't that mean that h1 is p > 0.3

[timid lotus]

Yeah

But

It’s two tailed

So it’s
H0:p=0.3
H1:p≠0.3

Wait uh no my bad no 😭

Read the q wrong yes it’s >

[floral bison]

yeh it's one tailed

under H0: X~B(20, 0.3)

work out P(X<=2)

if less than 0.05 reject H0, if not DO NOT reject - never say ACCEPT

there isn't sufficient evidence to actually straight up accept the null hypothesis, just enough to assert that the alternate hypothesis is too unlikely to be considered right

[wet oasis]

so is h1 meant to be p > 0.3 then

[floral bison]

yes 👍

[wet oasis]

so was the working out they done here wrong then for the hypothesises that they stated

[floral bison]

yeh, should be p > 0.3

t madas with an uncharacteristic mistake

[wet oasis]

that's a relief thanks

I'm struggling to determine what h1 is for this question though

I'm assuming it's be p < 0.4

[floral bison]

yep 👍

[wet oasis]

awesome
