(a)What is the sample test statistic? 0.458 1.774 -1.255 -1.744 (b)Do you reject or fail to reject the null hypothesis? Are the data statistically significant? Since the P-value is less than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis. 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. Since the P-value is less than the level of significance, the data are statistically significant. Thus, we fail to reject the null hypothesis. Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we reject the null hypothesis. (c)What is the P-value? .0435 .0869 .9565 .0471 (c)Which of the following is NOT true about the margin of error of a statistic? The margin of error measures, roughly, the average difference between the statistic and the population parameter. The margin of error can never be a negative number. The margin of error is the estimated standard deviation of the sampling distribution for the statistic. The margin of error increases as the sample size(s) increases.

(b)Do you reject or fail to reject the null hypothesis? Are the data statistically significant?
Since the P-value is less than the level of significance, the data are statistically significant. Thus, we reject the null hypothesis.
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.
Since the P-value is less than the level of significance, the data are statistically significant. Thus, we fail to reject the null hypothesis.
Since the P-value is less than the level of significance, the data are not statistically significant. Thus, we reject the null hypothesis.

(c)Which of the following is NOT true about the margin of error of a statistic?
The margin of error measures, roughly, the average difference between the statistic and the population parameter.
The margin of error can never be a negative number.
The margin of error is the estimated standard deviation of the sampling distribution for the statistic.
The margin of error increases as the sample size (s) increases.

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.
