The average number of accidents at controlled intersections per year is 5.7. Is this average less for intersections with cameras installed? The 58 randomly observed intersections with cameras installed had an average of 5.4 accidents per year and the standard deviation was 1. What can be concluded at the αα = 0.10 level of significance? For this study, we should use Select an answer z-test for a population proportion t-test for a population mean The null and alternative hypotheses would be: H0:H0: ? p μ Select an answer = > ≠ < H1:H1: ? μ p Select an answer ≠ > < = The test statistic ? z t = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? > ≤ αα Based on this, we should Select an answer reject accept fail to reject the null hypothesis. Thus, the final conclusion is that ... The data suggest that the population mean is not significantly less than 5.7 at αα =…
WebAssign -→ xC OD Let x represent the number of mountain dimbers killed each year. The long term variance of x is approximately o= 136.2. Suppose that for the past 7 years, the vanance has been sE 110.6.

The average American consumes 100 liters of alcohol per year. Does the average college student consume more alcohol per year? A researcher surveyed 13 randomly selected college students and found that they averaged 107.9 liters of alcohol consumed per year with a standard deviation of 19 liters. Assuming that the data come from a normally distributed population, what can be concluded at the the αα = 0.05 level of significance? The null and alternative hypotheses would be: The test statistic= The p-value =
A simple random sample of 101 course evaluations had a mean x¯x¯ = 3.90 with a standard deviation s = 0.52. Use a 0.05 significance level to test the claim that the population of course evaluations has a mean less than 4.00.
Scores on a certain "IQ" test for 18-25 year olds are normally distributed. A researcher believes that the average IQ score for students at a certain NJ college is less than 110 points, and so wants to test this hypothesis. The researcher obtain a SRS of 45 student IQ scores from school records and found the mean of the 45 results was 108 with a sample standard deviation of 21. The level of significance (alpha) used for this problem is 0.05. What is the appropriate test statistic (Student must complete by showing by formula using the ap- propriate values in that formula "showing work" and the final answer and appropriate label)?

A random sample of 23 bags of apples (marked as 10 pounds each) received by a large grocery chain tested out as having a mean of 9.2 pounds with a variance of 2.56 pounds. Test whether the true mean of all bags is under 10 pounds. Set up hypotheses. Perform the appropriate test by showing your formula. Interpret the results using a Type I (alpha) error of .05. Also provide the p value here. Also construct a 95% confidence interval around your sample mean (X bar) that should contain the true mean (mu). Also interpret this interval.
