- Perform a a Pearson’s correlation in SPSS to determine whether the weight of an automobile (‘weight’: Vehicle Weight-lbs) is significantly correlated with its horsepower (‘hp’: horse power). Use a two-tailed test with α = .01 The alternative hypothesis in symbols and null hypothesis in words is:The germination rate of seeds is defined as the proportion of seeds that, when properly planted and watered, sprout and grow. A certain variety of grass seed usually has a germination rate of 0.80, and a company wants to see if spraying the seeds with a chemical that is known to change germination rates in other species will change the germination rate of this grass species. (a) Suppose the company plans to spray a random sample of 400 seeds and conduct a two-sided test of 0: 0.8Hpusing = 0.05. They determine that the power of this test against the alternative 0.75pis 0.69. Interpret the power of this test.(b) Describe two ways the company can increase the power of the test. What is a disadvantage of each of these ways? (c) The company researchers spray 400 seeds with the chemical and 307 of the seeds germinate. This produces a 95% confidence interval for the proportion of seeds that germinate of (0.726, 0.809). Use this confidence interval to determine whether the test described in…From a sack of fruit containing 3 oranges, 2 apples, and 3 bananas, a random sample of 5 pieces of fruit is selected.
