Question

The average salary in this city is $40,500. Is the average more for single people? 61 randomly selected single people who were surveyed had an average salary of $46,124 and a standard deviation of $14,670. What can be concluded at the αα = 0.01 level of significance?

For this study, we should use Select an answer t-test for a population mean z-test for a population proportion
The null and alternative hypotheses would be:

H0:H0: ? p μ Select an answer = < > ≠

H1:H1: ? p μ Select an answer = > ≠ <

The test statistic ? t z = (please show your answer to 2 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is ? > ≤ αα
Based on this, we should Select an answer fail to reject reject accept the null hypothesis.
