Question 641101: A coin that is balanced should come up heads half the time in the long run. The population for coin tossing contains the results of tossing the coin forever. The parameter p os the probability of a head, which is the proportion of all tosses that give a head. A coin is tossed 4040 times and gives 2085 heads. Is the coin biased? Use alpha =.05

Is this HW # 8 Question 4?
Solution:
H0: p = 0.5
H1: p ≠ 0.5
Test Stat, z = 2.0453
Critical Values: �1.96
p-value = 0.0408
Reject the Null Hypothesis because the p-value is less than 0.05.
There is enough evidence to support the claim that the coin is biased.
