Q:
A coin is flipped 60 times. it landed on head 36 times. Do you think that the coin is biased?
------------------------------------------------------------------------------
A:
Null Hypothesis, H0: p = 0.5, The coin is unbiased.
Alternative Hypothesis, H1: p ≠ 0.5, The coin is biased.
Level of Significance: α = 0.05
Critical Values: �1.96
Test Statistic: z
sample proportion = 36/60 = 0.6

P-Value = 0.1213
Fail to reject the Null Hypothesis because the test statistic (1.5492) is between the lower (-1.96) and upper critical value (1.96). We do not have enough evidence to support the claim that the coin is biased.
