Identify the null hypothesis, alternative hypothesis, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Test the claim about the population mean u at the level of significance a. Assume the population is normally distributed. Claim:us 45; a = 0.01; 0 = 4.3 Sample statistics: x = 46.8, n = 40 Fail to reject Ho. There is enough evidence at the 1% level of significance to support the claim. Reject Ho. There is enough evidence...

Match each of the four p-values with the appropriate conclusion. p-value = .2035 p-value = .000073 p-value = .0713 p-value = .028 I. The result is statistically significant at the 5% level but not at the 1% level. II. The evidence against the null hypothesis is statistically significant at the 10% level, but not at the 5% level. III. The evidence against the null and in favor of the alternative hypothesis is extremely strong. IV. There is not...
