A poll summarized the results of a survey of 2,400 adults and 500 teens aged 13 to 17. It was reported that 32% of the teens surveyed and 39% of the adults surveyed indicated that they believe in reincarnation. The samples were selected to be representative of American adults and teens. n USE SALT Use the data from this survey to estimate the difference in the proportion of adults who believe in reincarnation and the proportion of teens who believe in reincarnation by calculating a 95% confidence interval for the difference. (Use padults - peens: Round your answers to three decimal places.) to Interpret your interval in context. O There is a 95% chance that the true difference between the proportion of adults who believe in reincarnation and the proportion of teens who believe in reincarnation is in the interval. Because both endpoints of the confidence interval are positive, we believe that the proportion of adults who believe in reincarnation is less than the proportion of teens aged…

A researcher is testing which animal performs better on the anxiety task that involves a stranger walking into the room. In one group they test dogs and another cats and see how long it takes the animal to approach the person “stranger”. Here is the data from 10 subjects that was recorded in seconds:Dogs: 120, 126, 140, 115, 112, 130, 125, 108, 128, 143Cats: 125, 140, 128, 133, 138, 129, 135, 129, 140, 125Which set of scores has a lower SEM? You should be able to do this just by looking at the raw scores, but of course you can do the math if it helps you answer the question.

A random sample of 50 plants was selected from a field containing one-year-old plants of a variety of guayule, a plant species yielding rubber. Of the 50, 25 were classified as Normal (N), 14 were classified as Off-type (O) and 11 as Aberrant (A). The data on the following page show the percentage rubber content from each plant. Normal Off-type Aberrant 6.34 6.40 5.70 4.84 5.01 6.20 4.25 8.90 6.93 6.38 6.68 7.10 6.42 7.26 7.29 6.30 7.01 6-84 7.12 6.83 7.31 7.25 6.86 6.68 5.82 4.46 7.70 5.90 5.24 5.58 6.36 7.10 6.81 7.32 6.48 5.88 5.24 5.51 7.00 6.42 6.20 6.04 5.58 4.72 7.42 7-27 6.43 6-10 6-01 7.90 (a) Test the null hypothesis that there is no difference in mean rubber content between the three types of plant. (b) If the means of the distributions of each type of plant are denoted by N, PO and PA respectively, test the following particular null hypotheses: (i) EN = RA; (ii) Po=(PN + PA).
