Step-by-step explanation:
1.
let's define p as the proportion of all correct guesses made by the octopus paul.
<u>null</u><u> </u><u>hypothesis</u>
h0: p = 0.5
<u>alter</u><u>native</u><u> hypothesis</u>
h1: p > 0.5
2.
<u>we</u><u> </u><u>are</u><u> </u><u>to</u><u> </u><u>get</u><u> </u><u>paul's </u><u>samp</u><u>le</u><u> </u><u>prop</u><u>ortion</u>
= p^ = 8/8 = 1
3.
<u>in</u><u> </u><u>this</u><u> </u><u>last</u><u> </u><u>que</u><u>stion</u><u> </u><u>we</u><u> </u><u>a</u><u>re</u><u> </u><u>to</u><u> </u><u>sta</u><u>te</u><u> </u><u>why</u><u> </u><u>this</u><u> </u><u>met</u><u>hod</u><u> </u><u>works</u><u> </u><u>for</u><u> </u><u>assumi</u><u>ng</u><u> </u><u>that</u><u> </u><u>null</u><u> </u><u>hypothesis</u><u> is</u><u> </u><u>true</u><u>.</u>
the reason is that the null hypothesis was stated as p = 0.5 and we know that a coin would land as head 50% or half of the time.
