Here the question asks.
00:01
A skeptic decides to conduct an experiment in esp in which a blindfolded subject calls out the color of a card dealt from a regular deck of cards.
00:09
Half the cards are red, the other half black.
00:11
100 cards are dealt from a well -shuffled pack with each card being replaced after a deal.
00:15
Using a 5 % level of significance, what is the lowest number of cards that the subject needs to call out correctly in order to show that he is doing better than he would if he were simply guessing.
00:25
We'll say lowest number.
00:30
That's what we're trying to find.
00:32
The hypotheses in the experiment are h -0 guessing.
00:39
We'll say the subject is guessing, but i'll just say it's guessing.
00:44
That will be p equals 0 .5.
00:48
And we'll say the alternative hypothesis...
