Students at the Akademia Podlaka conducted an experiment to determine whether the Belgium-minted Euro coin was equally likely to land heads up or tails up. Coins were spun on a smooth surface, and in 350 spins, 163 landed with the heads side up. Should the students interpret this result as convincing evidence that the proportion of the time the coin would land heads is not 0.5? A) Letting p denote the true probability of landing heads, state the sign of the alternative hypothesis. (type one of these 3 choices: greater than, less than, or not equal) ___________________. B) Calculate the test statistic for the test above. (round test statistic to 2 decimal places) ______________. C)What is the p-value here? (round to 2 decimal places) _____________. D) What's your decision on the hypothesis test above? Use significance level 0.05. (type Reject for Reject Ho, type FTR for Fail to Reject Ho) ______________.
