Find the margin of error for the given values of c, s, and n. c 0.90, s-2.7, n 29 Click the icon to view the t-distribution table. The margin of error is . (Round to one decimal place as needed.) Which value of r indicates a stronger correlation: 0.846 or0.933? Explain your reasoning. Choose the correct answer below A. r=-0.933 represents a stronger correlation because l-0.939 > 10.845. B. r0.846 represents a stronger correlation because 0.846> -0.933. C.-0.933 represents a...
this is concept. 2. A plant distills liquid air to produce oxygen, nitrogen, and argon. The percentage of impurity in the oxygen is thought to be linearly related to the amount of impurities in the air as measured by the pollution count" in part per million (ppm). A sample of plant operating data is shown below. Pollution count (ppm) Purity (%) 933 1145 1.59 92.4 91.7 94 1.08 Purity (%) 946 12 93.6 0.99 0.83 12 932 1.47 1.81 05...
