Question

Hello, I need help with task 3 which has 3question as it is part of one big question. Therefore 30 for a question for each. These questions are connected to previous ones so, I will send an image of the other two task

Answer 1

Task 3 (of 3)

Part 1: In this case the probabilitie that a person saw resould and receive the power pill is 0.65, so in order to have a trustable resould should be more than 95% to be certan. How ever I think that with a probabiliti of more that the 70% could wor. So in this case a probabilitie of 65% is not enogh to produce or dristribute.

Part 2: We can compare the resoulds of group A and group B and the resoulds of group C vs the resould in group D so we check if telling the subject affect anything.

So for group A and B are 0.15 and 0.175 so there is no significant difference and for C and the are 0.125 and 0.1 so there is again not significant effect.

Part 3: In this case maybe a better way to made the experiment is to take a bigger poblation, becuase each group has to low participants. if we have more particiants we can have better resoulds. Also we can calculate a standart deviation to be sure of the difference between the groups.
