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.

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 =

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.
