sted in constructing a 98% confidence interval for the proportion of samples of DNA evidence that correctly identify a criminal. 965 of the 1000 randomly selected DNA samples correctly identified the criminal. Round your answers to two decimal places. A. With 98% confidence the proportion of all DNA samples that correctly identify a criminal is between __________and___________. B. If many groups of 1000 randomly selected DNA samples were tested, then a different confidence interval would be produced from each group. About_________p

A 2008 study by the National Highway Traffic Safety Administration reported that 50% of all car crashes occur within 5 miles of the crashing person's home. Jill is skeptical of this report and believes that the true proportion of such crashes is more than 50%. Jill collects a random Close to home sample of 195 crashes and finds that 107 have occurred within 5 miles of the crashing person's home. Round all numeric answers to 4 decimal places. 1. What are the null and alternative hypotheses? Но р3 0.5000 v На p> 0.5000 2. Calculate the null standard error for this hypothesis test. SE = 0.0358 3. What is the test statistic for this hypothesis test? Z = 1.3601 4. Calculate the p-value. p = 0.0869 5. Based on the p-value, we have Some v evidence against the null hypothesis. 6. Which of the statements below are correct interpretations of the null standard error? You should choose all that are correct interpretations. A. The null standard error estimates the width of a confidence interval for…
