Assume that population mean is to be estimated from the sample described. Use the sample results to approximate the margin of error and 95% confidence interval. n = 36, x = 64.4 seconds, s = 6.5 seconds. The margin of error is seconds. (Round to one decimal place as needed.) an example 4
Psychology experiments sometimes involve testing the ability of rats to navigate a maze. One researcher needs a maze that will take rats, on average, less than a minute to solve. The data below (image provided) gives the completion times for this maze for 20 randomly sampled rats. Will the maze fulfill the researcher’s time requirement? Use a significance level of ? = 0.05. What are the hypotheses. What are the test statistic and p-value. What is the full conclusion for this test in the context of the problem.

In a study of speed dating, male subjects were asked to rate the attractiveness of their female dates, and a sample of the results is listed below (1 = not attractive; 10 = extremely attractive). Construct a confidence interval using a 99% confidence level. What d the results tell about the mean attractiveness ratings of the population of all adult females? 7, 9, 3, 8, 5, 4, 8, 8, 7, 10, 5, 9 O What is the confidence interval for the population mean µ? <µ< (Round to one decimal place as needed.) What does the confidence interval tell about the population of all adult females? Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The results tell nothing about the population of all adult females, because participants in speed dating are not a representative sample of the population of all adult females. O B. We are 99% confident that the interval from to actually contains the true mean attractiveness rating of all adult females.…

Early-childhood-development studies indicate that the more often a child is read to from birth, the earlier the child begins to read. A local parents’ group wants to test this theory and samples families with young children. They find the following results. Construct a 99% confidence interval to estimate the true difference between the proportions of children who read at an early age when they are read to frequently compared to those who were read to less often, as described in the table of results. Let Population 1 be the children who were read to frequently and Population 2 be the children who were read to less often. Round the endpoints of the interval to three decimal places, if necessary. Ages when Children Begin to Read Read to at Least Three Times per Week Read to Fewer than Three Times per Week Started Reading by age 4 60 35 Started Reading after age 4 36 51 Lower end point: Upper end point:
