What can be concluded at the o: = 0.10 level of significance? 0 a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: :1 :1 H0: ? G Select an answer 0 H1: ? G Select an answer 0 c. The test statistic ? c = I:] (please show your answer to 3 decimal places.) d. The p-value = [: (Please show your answer to 4 decimal places.) e. The p-value is ? c a: f. Based on this, we should Select an answer 6 the null hypothesis. g. Thus, the final conclusion is that O The data suggest that the populaton mean is significantly less than 48,000 at a: = 0.10, so there is statistically significant evidence to conclude that the population mean salary for singles is less than 48,000. 0 The data suggest that the sample mean is not significantly less than 48,000 at o: = 0.10, so there is statistically insignificant evidence to conclude that the sample mean salary for singles is less than 46,760. 0 The data suggest that the population mean is not significantly less than 48,000 at a = 0.10, so there is statistically insignificant evidence to conclude that the population mean salary for singles is less than 48,000. h.
