An agricultural field trial compares the yield of two varieties of corn. The researchers divide in half each of 20 fields of land in different locations and plant each corn variety in one half of each plot. After harvest, the yields are compared in bushels per acre at each location. The 20 differences (Variety A - Variety B) givex¯=3.2x¯=3.2 and s=4.63s=4.63. Does this sample provide evidence that Variety A had a higher yield than Variety B? (a) State the null and alternative hypotheses: (Type "mu" for the symbol μμ , e.g. mu >> 1 for the mean is greater than 1, mu << 1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1) H0H0 : HaHa : (b) Find the test statistic, t = (c) Answer the question: Does this sample provide evidence that Variety A had a higher yield than Variety B?

The fitted regression Computer power dissipation=14.82 +0.049 Microprocessor speed, where Computer power dissipation is measured in watts and Microprocessor speed is measured in MHz. (a-1) If Microprocessor speed = 1 MHz, then Computer power dissipation = (a-2) Choose the correct statement. (b) O An increase in the microprocessor speed decreases the computer power dissipation. O An increase in the microprocessor speed increases the computer power dissipation. O A decrease in microprocessor speed increases the computer power dissipation. If Microprocessor speed = 2,900 MHz, then Computer power dissipation = watts. (Round your answer to 3 decimal places.) (c) Choose the right option. watts. (Round your answer to 2 decimal places.) O The Intercept would be meaningful because you would have a computer with zero speed. O The Intercept would not be meaningful because you would not have a computer with zero speed.
