The Toylot company makes an electric train with a motor that it claims will draw an average of only 0.8 ampere (A) under a normal load. A sample of nine motors was tested, and it was found that the mean current was x= 1.22 A, with a sample standard deviation of s = 0.44 A. Do the data indicate that the Toylot claim of 0.8 A is too low? (Use a 1% level of significance.)1. What are we testing in this problem?a. single proportionb. single mean2. What is the level of significance?3. State the null and alternate hypotheses.4. What sampling distribution will you use? What assumptions are you making?a. The Student's t, since we assume that x has a normal distribution with known b. The standard normal, since we assume that x has a normal distribution with known .c. The standard normal, since we assume that x has a normal distribution with unknown .d. The Student's t, since we assume that x has a normal distribution with unknown .

What is the averagevelocity for the trip? The text states, "Over sufficiently long time periods, net income equals cash inflows minus cash outflows, other than cash flows with owners." Demonstrate the accuracy of this statement in the following scenario: Two friends contributed $50,000 each to form a new business. The owners used the amounts contributed to purchase a machine for $100,000 cash. They estimated that the useful life of the machine was five years and the salvage value was $20,000. They rented out the machine to a customer for an annual rental of $25,000 a year for five years. Annual cash operating costs for insurance, taxes, and other items totaled $6,000 annually. At the end of the fifth year, the owners sold the equipment for $22,000, instead of the $20,000 salvage value initially estimated. (Hint: Compute the total net income and the total cash flows other than cash flows with owners for the five-year period as a whole.) write down in terms of n, an expression for the nth term of the following sequences 2 5 8 11 14 Your class has been chosen to select a new food to be served in the cafeteria.
