The average number of accidents at controlled intersections per year is 5.3. Is this average a different number for intersections with cameras installed? The 69 randomly observed Intersections with cameras installed had an average of 4.9 accidents per year and the standard devlation was 1.18. What can be concluded at the a = 0.05 level of signtficance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?vSelect an answerv H: ?vSelect an answerv c. The test statistic ?v = (please show your answer to 3 decimal places.) d. The p-value (Please show your answer to 4 decimal places.) %3D e. The p-value is ?v a f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest that the sample mean is not significantly different from 5.3 at a = 0.05, so there is statistically insignificant evidence to conclude that the sample mean number of accidents per year at intersections with cameras installed is different from 4.9 accidents. %3D O The data suggest that the populaton mean is significantly different from 5.3 at a = 0.05, so there is statistically significant evidence to conclude that the population mean number of accidents per year at intersections with cameras installed is different from 5.3 accidents. %3!

O If the population mean number of accidents per year at intersections with cameras installed is 5.3 and if another 69 intersections with cameras installed are observed then there would be a 0.63608122% chance that the sample mean for these 69 intersections with cameras installed would either be less than 4.9 or greater than 5.7. O There is a 0.63608122% chance that the population mean number of accidents per year at intersections with cameras installed is not equal to 5.3.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
