The average salary in this city is $45,700. Is the average more for single people? 64 randomly selected
single people who were surveyed had an average salary of $48,911 and a standard deviation of $17,630.
What can be concluded at the a 0.01 level of significance?

(please show your answer to 3 decimal places.)
(Please show your answer to 4 decimal places.)
f. Based on this, we should [Select an answer the null hypothesis.
g. Thus, the final conclusion is that...
O The data suggest that the population mean is not significantly greater than 45,700 at a =
0.01, so there is statistically insignificant evidence to conclude that the population mean
salary for singles is greater than 45,700.

Production costs are $50, $80, $40, and $70 per unit during these months. The storage cost from one month to the next is $20 per unit (assessed on ending inventory). It is estimated that each unit on hand at the end of month 4 can be sold for $60. Assume there is no beginning inventory. Determine how to minimize the net cost incurred in meeting the demands for the next four months. Use SolverTable to see what happens to the decision variables and the total cost when the initial inventory varies from 0 to 1000 in 100-unit increments. How much lower would the total cost be if the company started with 100 units in inventory, rather than none? Would this same cost decreasearrow_forward
