A corporation maintains a large fleet of company cars for Its sales people. To check the average number of miles driven per mont
h per car this year, a random sample of 40 cars is examined. The mean and standard deviation for the samples are 2752 mi/mo., and 350 mi/mo., respectively. It is known that the average number of miles driven per car per month was 2600 and sigma = 350 from the previous records. Test the claim that the mean mileage driven per car per month is different from that of the previous records. Let alpha = 0.05. a. State the requirements. Does it meet the appropriate requirements? b. State H_0 and H_a. c. Compute the test statistic. d. Find the critical value and p value. State your conclusion and interpret.
The quick ratio, QQQ, is calculated using the formula Q = \dfrac{CA-I - P}{CL}Q= CL/CA−I−P Q, equals, start fraction, C, A, minus, I, minus, P, divided by, C, L, end fraction, where CACAC, A is the value of the company's current assets, III is inventory, PPP is prepaid expenses, and CLCLC, L is current liabilities.
