Assume that the hay fever rate in each age group has an approximately normal distribution. Do the data indicate that the age group over 50 has a lower rate of hay fever? Use a =0.05. If 0.025 < P-value <0.05, will you reject or fail to reject the null hypothesis? Are the data statistically significant at confidence level a? O Since the P-value is greater than the level of significance, the data are statistically significant. Thus, we fail to reject the null hypothesis. O Since the P-value is greater than the level of significance, the data are not statistically significant. Thus, we fail to reject the null hypothesis. O Since the P-value is greater than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis. Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we fail to reject the null hypothesis. O Since the P-value is greater than the level of significance, the data are not statistically significant. Thus, we reject the null hypothesis.
