The average number of accidents at controlled intersections per year is 5.2. Is this average a differentnumber for intersections with cameras installed? The 48 randomly observed intersections with camerasinstalled had an average of 4.2 accidents per year and the standard deviation was 1.98. What can beconcluded at the a = 0.05 level of significance?a. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Ho: ? Select an answerH₁:?✓ Select an answer ✓c. The test statistic ? ✓d. The p-value=e. The p-value is ? ✓ af. Based on this, we shouldg. Thus, the final conclusion is that ...(please show your answer to 3 decimal places.)(Please show your answer to 4 decimal places.)Select an answer the null hypothesis.O The data suggest that the population mean is not significantly different from 5.2 at a = 0.05,so there is statistically insignificant evidence to conclude that the population mean number ofaccidents per year at intersections with cameras installed is different from 5.2 accidents.O The data suggest that the population mean is significantly different from 5.2 at a = 0.05, sothere is statistically significant evidence to conclude that the population mean number ofaccidents per year at intersections with cameras installed is different from 5.2 accidents.The data suggest that the sample mean is not significantly different from 5.2 at a = 0.05, sothere is statistically insignificant evidence to conclude that the sample mean number ofaccidents per year at intersections with cameras installed is different from 4.2 accidents.
