### Problem Context:Based on a survey, 36% of likely voters would be willing to vote by internet instead of the in-person traditional method of voting. For each of the following, assume that 15 likely voters are randomly selected. Complete parts (a) through (c) below.---### Question:**0.00057** *(Round to five decimal places as needed.)***a.** If 12 of the selected voters would do internet voting, is 12 significantly high? Why or why not?Select the correct choice below and fill in the answer box within your choice.*(Round to five decimal places as needed.)*- A. No, because the probability of 12 or more is ___, which is low.- B. Yes, because the probability of 12 or more is ___, which is low.- C. Yes, because the probability of 12 or more is ___, which is not low.- D. No, because the probability of 12 or more is ___, which is not low.---### Notes for Educational Website:This problem is part of a statistics exercise on determining statistical significance in probabilistic scenarios. It involves analyzing survey data and using probability to interpret the likelihood of certain outcomes. The aim is to help learners understand the concept of statistical significance and how it applies to real-world data analysis.- **Key Concept Explored:** Statistical significance and probability.- **Skills Practiced:** Calculating probabilities, interpreting survey data, and making data-driven decisions.

Twelve runners are asked to run a 10-kilometer race on each of two consecutive weeks. In one of the races, the runners wear one brand of shoe and in the other, a different brand. The brand of shoe they wear in each race is determined at random. All runners are timed and are asked to run their best in each race. The results (in minutes) are given below. Runner Brand 1 Brand 2 1 31.23 32.02 2 29.33 28.98 3 30.50 30.63 4 32.20 32.67 5 33.08 32.95 6 31.52 31.53 7 30.68 30.83 8 31.05 31.10 9 33.00 33.12 10 29.67 29.50 11 30.55 30.57 12 32.12 32.20 Use the sign test for matched pairs to determine if there is evidence that times using Brand 1 tend to be faster than times using Brand 2.

Solve the problem. At the Jumping Jack cookie factory, quality assurance inspectors remove broken or otherwise defective cookies from a moving conveyor belt prior to packaging. Based on past studies, the plant manager knows that the inspectors eliminate 98% of the defective cookies at a conveyor belt speed of 9 feet per minute. As the belt speed increases, the factory can produce more cookies per hour, but at the cost of lower quality of the packaged product. Inspectors collect only 60% of defective cookies at a belt speed of 18 feet per minute.
