Sloan transmissions, inc., has the following estimates for its new gear assembly project: price = $2,600 per unit; variable costs = $520 per unit; fixed costs = $1.7 million; quantity = 82,000 units. suppose the company believes all of its estimates are accurate only to within ±20 percent. what values should the company use for the four variables given here when it performs its best-case scenario analysis? what about the worst-case scenario?

Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 3%. a mutual-fund rating agency randomly selects 27 months and determines the rate of return for a certain fund. the standard deviation of the rate of return is computed to be 2.19%. is there sufficient evidence to conclude that the fund has moderate risk at the alpha equals 0.05 level of significance? a normal probability plot indicates that the monthly rates of return are normally distributed.
