Question

Students 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 260 spins, 140 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 up is not 0.5? Test the relevant hypotheses using $\alpha = 0.01$. Would your conclusion be different if a significance level of 0.05 had been used? (Round your test statistic to two decimal places and your $P$-value to four decimal places.) $z = $ $p = $ For $\alpha = 0.01$ There is ---Select--- evidence to suggest that the proportion of the time that the Belgium Euro coin would land with its head side up is not 0.5. For $\alpha = 0.05$ There is ---Select--- evidence to suggest that the proportion of the time that the Belgium Euro coin would land with its head side up is not 0.5. You may need to use the appropriate table in Appendix A to answer this question. Additional Materials eBook
