This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 285. Assume that the population standard deviation is 32. At a = 0.14, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). (a) Write the claim mathematically and identify Ho and Ha. Choose the correct answer below.

One part of the study showed the "beliefs about God" for people who were either "affiliated with a religion" or "unaffiliated with a religion." The possible categories for beliefs in God are "Believe in a higher power", "sometimes believe", "don't believe", and “believe with doubts." Here are the observed frequencies for a Chi-square test of association and we have added the row and column totals. Believe Sometimes Don't Believe Total Believe Believe with doubts affiliated w relig 90 40 10 60 200 unaffiliated w rel 50 30 15 100 Total 140 70 15 75 300 We want to do a Chi-Square test of association for religious affiliation versus belief in God. What is the expected frequency for the "affiliated w relig" and "Believe" category? Round your answer to the tenths position.The Elisa test for the human immunodeficiency virus (HIV) that causes AIDS has been used in the screening of blood donations. As with most medical diagnostics test, the ELISA test is not infallible. If a person actually carries HIV, experts estimate that this test gives a positive result 97.7% of the time (the number is called the sensitivity of the test. If a person does not carry HIV ELISA gives a negative result 92.6% of the time. Suppose that 0.5% of the public carries HIV.

- The Trial Urban District Assessment (TUDA) is a government-sponsored study of student achievement in large urban school districts. TUDA gives a mathematics test scored from 0 to 500. A score of 262 is a "basic" mathematics level, and a score of 299 is "proficient." Scores for a random sample of 1100 eighth-graders in Dallas had x = 264 with standard error 1.3. TUDA results for 2019 from the National Center for Education Statistics, at https://www.nationsreportcard.gov. LO 5 DEC 1 S tv ♫ ♫ O Macmillan Learning (c) Is there good evidence that the mean for all Dallas eighth-graders is different from the basic level? F8 OYes, because the sample mean of 264 is not included in the 99% confidence interval. Yes, because the basic level of 262 is not included in the 99% confidence interval. O No, because the basic level of 262 is included in the 99% confidence interval. O No, because the sample mean of 264 is included in the 99% confidence interval.
