The average number of accidents at controlled intersections per year is 5.8. Is this average a differentnumber for intersections with cameras installed? The 46 randomly observed intersections with camerasinstalled had an average of 6.1 accidents per year and the standard deviation was 0.83. What can beconcluded at the a 0.01 level of significance?a. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Select an answer YH: 7Select an answer Yc. The test statistic ? v(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)%De. The p-value is ? af. Based on this, we should Select an answer v the null hypothesis.g. Thus, the final conclusion is that ...O The data suggest that the sample mean is not significantly different from 5.8 at a = 0.01, sothere is statistically insignificant evidence to conclude that the sample mean number ofaccidents per year at intersections with cameras installed is different from 6.1 accidents.O The data suggest that the population mean is not significantly different from 5.8 at a = 0.01,so there is statistically insignificant evidence to conclude that the population mean number ofaccidents per year at intersections with cameras installed is different from 5.8 accidents.O The data suggest that the populaton mean is significantly different from 5.8 at a = 0.01, sothere is statistically significant evidence to conclude that the population mean number ofaccidents per year at intersections with cameras installed is different from 5.8 accidents.h. Interpret the p-value in the context of the study.O There is a 1.81758026% chance that the population mean number of accidents per year atintersections with cameras installed is not equal to 5.8.O If the population mean number of accidents per year at intersections with cameras installed is5.8 and if another 46 intersections with cameras installed are observed then there would be a1.81758026% chance that the sample mean for these 46 intersections with cameras installedwould either be less than 6 or greater than 6.1.O There is a 1.81758026% chance of a Type I error.O If the population mean number of accidents per year at intersections with cameras installed is5.8 and if another 46 intersections with cameras installed are observed then there would be a1.81758026% chance that the population mean would either be less than 6 or greater than 6.1.i. Interpret the level of significance in the context of the study.O There is a 1% chance that the population mean number of accidents per year at intersectionswith cameras installed is different from 5.8.O If the population population mean number of accidents per year at intersections with camerasinstalled is different from 5.8 and if another 46 intersections with cameras installed areobserved then there would be a 1% chance that we would end up falsely concluding that thepopulation mean number of accidents per year at intersections with cameras installed is equalto 5.8.O There is a 1% chance that you will get in a car accident, so please wear a seat belt.O If the population mean number of accidents per year at intersections with cameras installed is5.8 and if another 46 intersections with cameras installed are observed then there would be a1% chance that we would end up falsely concluding that the population mean number ofaccidents per year at intersections with cameras installed is different from 5.8.

For a sample of n = 20 women aged 18 to 29, responses to the question “How tall would you like to be?" are recorded along with actual heights. In the sample, the mean desired height is 66.7 inches, the mean actual height is 64.9 inches, and the sample mean difference (desired - actual) is 1.8 inches. The sample standard deviation of the differences is 2.1 inches. Researchers hypothesize that, on average, women desire to be taller than they actually are. State the null and alternative hypotheses. What assumptions do we need in order for the conditions of the hypothesis test procedure to be met since the sample size is 20? Assuming necessary conditions are met, carry out the remaining steps of the hypothesis test (test statistic, p-value, decision, and conclusion in context).

You were told that the mean daily cost of a hotel room in downtown St. Louis is $120. You will be needing to rent a hotel room there in the near future and you want to find the best rate. You randomly select a sample of 18 hotel rooms and find that the average cost is $121.33 with a standard deviation of $18.046. At the α = 0.05 significance level, determine if there is enough evidence to reject the claim. What is the decision for this hypothesis test? You were told that the mean daily cost of a hotel room in downtown St. Louis is $120. You will be needing to rent a hotel room there in the near future and you want to find the best rate. You randomly select a sample of 18 hotel rooms and find that the average cost is $121.33 with a standard deviation of $18.046. At the α = 0.05 significance level, determine if there is enough evidence to reject the claim. What is the decision for this hypothesis test? Reject the null because the test statistic is in the critical region and the…
According to a large oil company, the average cost per barrel of oil last year was $47. You believe that due to the current oil crisis in Russia and Iran that the cost of a barrel of oil has decreased. You collect a simple random sample of 60 barrels of oil and find an average price of $42 and a standard deviation of $12.
