A systems analyst tests a new algorithm designed to work faster than the currently-used algorithm. Each algorithm is applied to a group of 51 51 sample problems. The new algorithm completes the sample problems with a mean time of 24.43 24.43 hours. The current algorithm completes the sample problems with a mean time of 24.68 24.68 hours. The standard deviation is found to be 3.481 3.481 hours for the new algorithm, and 3.420 3.420 hours for the current algorithm. Conduct a hypothesis test at the 0.05 0.05 level of significance of the claim that the new algorithm has a lower mean completion time than the current algorithm. Let μ1 μ 1 be the true mean completion time for the new algorithm and μ2 μ 2 be the true mean completion time for the current algorithm. Step 2 of 4: Compute the value the test statistic. Round to two decimal places.

We Bring the Rain Irrigation Company is currently growing much
faster than the economy. Expected growth of the company is 16% for
the next 4 years; then it is expected to settle down to a constant
3% growth rate thereafter. The dividend last year was $3.20.
Investors' required return on stocks of similar risk is 8%. If you
already own 500 shares of We Bring the Rain, what should you do
based on a comparison between your calculated intrinsic value...
