Answer:
p value = 0.3122
Step-by-step explanation:
Given that Pedro thinks that he has a special relationship with the number 3. In particular,
Normally for a die to show 3, probability p =
Or proportion p = 0.1667
Pedro claims that this probability is more than 0.1667
where P is the sample proportion.
b) n=30 and
Mean difference =
Std error for proportion =
Test statistic Z = p difference/std error = 0.4894
p value = 0.3122
p >0.05
So not significant difference between the two proportions.
