Is a new method of teaching reading to first graders (Method B) more effective than the method now in use (Method A)? You design a matched pairs experiment to answer this question. You form 20 pairs of first graders, with two children in each pair carefully matched by IQ, socioeconomic status, and reading-readiness score. You assign at random one student from each pair to Method A. The other student in the pair is taught by Method B. At the end of the first grade, all the children take a test to determine their reading skill. Assume that the higher the score on this test, the more proficient the student is at reading. Let p stand for the proportion of all possible matched pairs of children for which the child taught by Method B has the higher score. Your hypotheses are Ho: p = 0.5 (no difference in effectiveness) Ha:p > 0.5 (Method B is more effective) 12 = 0.6. 20 The result of your experiment is that Method B gave a higher score in 12 of the 20 pairs, or p If Ho is true, the 20 pairs…
To assess the effectiveness of a cola video ad for cola B, a random sample of 35 individuals from a target audience was selected to participate in a copy test. Participants viewed two ads, one of which was the ad being tested (cola B). Participants then answered a series of questions about how much they liked the ads. An adindex measure was created and shown in the accompanying table; the higher the adindex value, the more likeable the ad. State your findings and conclusions. Assume α = 0.05. ( H₁: HD <0 Determine the test statistic, tSTAT · tSTAT = (Round to two decimal places as needed.) Find the p-value for the test statistic. The p-value is. (Round to three decimal places as needed.) State your conclusion. Ho. There H₁: HD 0 ( ...) ▼ sufficient evidence to conclude that the mean adindex ratings are higher for cola B than for cola A.
