The average number of accidents at controlled intersections per year is 5.4. Is this average more for intersections with cameras installed? The 47 randomly observed intersections with cameras installed had an average of 5.9 accidents per year and the standard deviation was 1.08. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho:? Select an answer H₁: ? Select an answer c. The test statistic ? ✓ (please show your answer to 3 decimal places.)

Question
The average number of accidents at controlled intersections per year is 5.4. Is this average more for intersections with cameras installed? The 47 randomly observed intersections with cameras installed had an average of 5.9 accidents per year and the standard deviation was 1.08. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? Select an answer ✓ H₁: ? Select an answer c. The test statistic ? = d. The p-value = e. The p-value is ? a f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) O The data suggest that the populaton mean is significantly more than 5.4 at a = 0.01, so there is statistically significant evidence to conclude that the population mean number of accidents per year at intersections with cameras installed is more than 5.4 accidents. O The data suggest that the population mean is not significantly more than 5.4 at a = 0.01, so there is statistically insignificant evidene to conclude that the population mean number of accidents per year at intersections with cameras installed is more than 5.4 accidents. O The data suggest that the sample mean is not significantly more than 5.4 at a = 0.01, so there is statistically insignificant evidence to conclude that the sample mean number of accidents per year at intersections with cameras installed is more than 5.9 accidents. h. Interpret the p-value in the context of the study. O There is a 0.13407982 % chance that the population mean number of accidents per year at intersections with cameras installed is greater than 5.4. O There is a 0.13407982 % chance of a Type I error. O If the population mean number of accidents per year at intersections with cameras installed is 5.4 and if another 47 intersections with cameras installed are observed then there would be a 0.13407982% chance that the population mean number of accidents per year at intersections with cameras installed would be greater than 5.4. O If the population mean number of accidents per year at intersections with cameras installed is 5.4 and if another 47 intersections with cameras installed are observed then there would be a 0.13407982% chance that the sample mean for these 47 intersections with cameras installed
