True or False and why Theodore is trying to determine whethe

True or False and why. Theodore is trying to determine whether a coin is fair. He flips the coin 100 times and counts the number of times heads comes up. He then computes a z-test statistic of zero. His z-test statistic indicated tha he must necessarily have observed the same number of head as tails?

Solution

True

For z statistic to be zero, the obtained proportion of heads must be equal to 0.5.

Hence number of heads= number if tails.
