Question

The average hourly wage of computer programmers with 2 years of experience has been $23.10. Because of high demand for computer programmers, it is believed there has been a significant increase in the average hourly wage of computer programmers. To test whether or not there has been an increase, which of the following are the correct hypotheses to be tested?

a. Null hypothesis: There has been no increase in the average hourly wage of computer programmers. Alternate hypothesis: There has been an increase in the average hourly wage of computer programmers.
b. Null hypothesis: There has been an increase in the average hourly wage of computer programmers. Alternate hypothesis: There has been no increase in the average hourly wage of computer programmers.
c. Null hypothesis: There has been a significant increase in the average hourly wage of computer programmers. Alternate hypothesis: There has been no increase in the average hourly wage of computer programmers.
d. Null hypothesis: There has been no increase in the average hourly wage of computer programmers. Alternate hypothesis: There has been a significant increase in the average hourly wage of computer programmers.

Answer 1

The correct hypotheses to be tested in this scenario are the null hypothesis and the alternative hypothesis.

Step-by-step explanation:

The correct hypotheses to be tested in this scenario are:

Null hypothesis: There has been no increase in the average hourly wage of computer programmers.

Alternative hypothesis: There has been an increase in the average hourly wage of computer programmers.

The null hypothesis assumes that there has been no change in the average hourly wage, while the alternative hypothesis suggests that there has been an increase. By conducting the appropriate statistical tests, we can determine whether there is sufficient evidence to reject the null hypothesis and support the alternative hypothesis.
