The average salary in this city is $46,700. Is the average different for single people? 53 randomly selected single people who were surveyed had an average salary of $48,860 and a standard deviation of $9,210. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b.

Question
The average salary in this city is $46,700. Is the average different for single people? 53 randomly selected single people who were surveyed had an average salary of $48,860 and a standard deviation of $9,210. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v Select an answer v H1: Select an er v answe c. The test statistic ? (please show your answer to 3 decimal places.) d. The p-value = e. The p-value is ? va f. Based on this, we should Select an answer v the null hypothesis. (Please show your answer to 4 decimal places.) g. Thus, the final conclusion is that .. O The data suggest that the sample mean is not significantly different from 46,700 at a = 0.05, so there is statistically insignificant evidence to conclude that the sample mean salary for singles is different from 48,860. O The data suggest that the population mean is not significantly different from 46,700 at a = 0.05, so there is statistically insignificant evidence to conclude that the population mean salary for singles is different from 46,700. O The data suggest that the populaton mean is significantly different from 46,700 at a = 0.05, so there is statistically significant evidence to conclude that the population mean salary for singles is different from 46,700. h. Interpret the p-value in the context of the study. O There is a 9.3789018% chance of a Type l error. O If the population mean salary for singles is $46,700 and if another 53 singles are surveyed then there would be a 9.3789018% chance that the population mean would either be less than 544,541 or greater than $48,860. O lf the population mean salary for singles is $46,700 and if another 53 singles are surveyed then there would be a 9.3789018% chance that the sample mean for these 53 singles surveyed would either be less than S44,541 or greater than $48,860. There is a 9.3789018% chance that the population mean salary for singles is not equal to $46,700. i. Interpret the level of significance in the context of the study. O f the population population mean salary for singles is different from $46,700 and if another 53 singles are surveyed then there would be a 5% chance that we would end up falsely concluding that the population mean salary for singles is equal to $46,700. O There is a 5% chance that you won the lottery, so you may not have to even have to worry about passing this class. O f the population mean salary for singles is $46,700 and if another 53 singles are surveyed then there would be a 5% chance that we would end up falsely concluding that the population mean salary for singles is different from $46,700. O There is a 5% chance that the population mean salary for singles is different from $46,700.
