The average salary for American college graduates is 540,300. You suspect that the average is different for graduates from your college. The 46 randomly selected graduates from your college had an average salary of $42,838 and a standard deviation of $9,000. What can be concluded at the a= 0.10 level of significance? %3! a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v Select an answer H1: 2 v Select an answer C. The test statistic ?

Thus, the final conclusion is that... the null hypothesis. O The data suggest that the populaton mean is significantly different from 40,300 at a = 0.10, so there is statistically significant evidence to conclude that the population mean salary for graduates from your college is different from 40,300. O The data suggest that the population mean is not significantly different from 40,300 at a = 0.10, so there is statistically insignificant evidence to conclude that the population mean salary for graduates from your college is different from 40,300. O The data suggest that the sample mean is not significantly different from 40,300 at a = 0.10, so there is statistically insignificant evidence to conclude that the sample mean salary for graduates from your college is different from 42,838. h.

h. Interpret the p-value in the context of the study. O There is a 6.216452% chance of a Type I error. O There is a 6.216452% chance that the population mean salary for graduates from your college is not equal to $40,300 . OIf the population mean salary for graduates from your college is $40,300 and if another 46 graduates from your college are surveyed then there would be a 6.216452% chance that the population mean would either be less than $37,762 or greater than $42,838. O If the population mean salary for graduates from your college is $40,300 and if another 46 graduates from your college are surveyed then there would be a 6.216452% chance that the sample mean for these 46 graduates from your college would either be less than $37,762 or greater than $42,838. i. Interpret the level of significance in the context of the study. Oif the population population mean salary for graduates from your college is different from $40,300 and if another 46 graduates from your college are surveyed then there would be a 10% chance that we would end up falsely concluding that the population mean salary for graduates from your college is equal to $40,300. O if the population mean salary for graduates from your college is $40,300 and if another 46 graduates from your college are surveyed then there would be a 10% chance that we would end up falsely concluding that the population mean salary for graduates from your college is different from $40,300.
