fill in the blanks

The average salary in this city is $47,000. Is the average more for single people? 33 randomly selected single people who were surveyed had an average salary of $51,110 and a standard deviation of $16,270. What can be concluded at the α = 0.10 level of significance? Use the classical approach. a. For this study, we should use [t-test for a population mean q b. The null and alternative hypotheses would be: Ho: H₁: An UV c. The test statistic t = d. The critical value =+ e. The test statistic is f. Based on this, we should reject (please show your answer to 3 decimal places.) (Please show your answer to 3 decimal places.) OF in the rejection region. the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest that the sample mean is not significantly greater than 47,000 at a = 0.10, so there is statistically insignificant evidence to conclude that the sample mean salary for singles is greater than 51,110. The data suggest that the populaton mean is significantly greater than 47,000 at a = 0.10, so there is statistically significant evidence to conclude that the population mean salary for singles is greater than 47,000. O The data suggest that the population mean is not significantly greater than 47,000 at a = 0.10, so there is statistically insignificant evidence to conclude that the population mean salary for singles is greater than 47,000.
