(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.
