A company which designs sports shoes has made an improvement to their popular running shoe. They hope that athletes wearing the new running shoe will be able to run faster over short distances. They will use a paired sample to determine whether the mean time to run 100 meters for sprinters wearing the new running shoe is less than the mean time to run the 100 meters for sprinters wearing the old running shoe. Determine the null and alternative hypotheses for the proposed hypothesis test. O A. Let u, denote the mean time to run 100 meters for sprinters wearing the new running shoe and let µ2 denote the mean time to run 100 meters for sprinters wearing the old running shoe. The null and alternative hypotheses are Họ: H1 > H2 and Ha: H1 H2. OC. Let u, denote the mean time to run 100 meters for sprinters wearing the new running shoe and let µ2 denote the mean time to run 100 meters for sprinters wearing the old running shoe. The null and alternative hypotheses are Họ: H1 = H2 and Hai Hy SH2. O D. Let u, denote the mean time to run 100 meters for sprinters wearing the new running shoe and let µ2 denote the mean time to run 100 meters for sprinters wearing the old running shoe. The null and alternative hypotheses are Ho: H1 2 H2 and Ha: H1

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
