- Find the critical Chi-square value for 0.05 significance level and 19 degrees of freedom. Give your answer to 3 decimal places.What does ANOVA technique describes?I am setting a new standard assessment and want the pass rate in the population to be 90%. As a trial, I select 150 participants and ask them to complete the standard assessment. I achieve 129 passes and 21 fails. · Null Hypothesis: Population Pass Rate equals 0.9 ● Alternative Hypothesis: Population Pass Rate not equal to 0.9* Are the assumptions satisfied for me to proceed with the test? Yes, I have at least 10 passes and 10 fails O Yes, but I must use t instead of Z as the sample size is not very large Yes, the sample size of 150 exceeds 30 so the central limit theorem will hold Ne
- You want to obtain a sample to estimate the proportion of a population that possess a particular genetic marker. Based on previous evidence, you believe approximately p*= 25% of the population have the genetic marker. You would like to be 90% confident that your estimate is within 1.5% of the true population proportion. How large of a sample size is required? n = Do not round mid-calculation. However, you may use a critical value accurate to three decimal places.The U.S. Department of Health monitors fishing waters, to determine if the bacteria count has risen above a maximum safe level of 70. The following observations were obtained from 9 random samples of a stream: 69, 74, 75, 70, 72, 73, 71, 73, and 68. Can you say that the bacteria are above the safe level (alpha=0.05)? Calculate the appropriate test statistic. What is the critical value for the test? Would you issue a warning about the bacteria levels in the stream? Why?The sample proportion, p¯p¯, will be within a distance of------------ from the population proportion, eighty percent of the time.Round your answer to 4 decimal places. Thank you for your assistance
- A survey was conducted two years ago asking college students their top motivations for using a credit card. You think the distribution has changed. You randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the distribution? Use a=0.10. 1. Determine the critical value, and the rejection region. 2. Calculate the test statistic.What are the two critical values? Round to three or more decimal places.A random sample of 28 records of automobile driver fatalities in kit carson coybry showed 15 involved an intoxicated driver.
