Truck pollution: In an experiment to determine the effect of ambient temperature on the emissons of oxides of nitrogen (wo,) of diesel trucks, 10 trucks were run at temperatures of 40 F and so F. The emissions, in parts per billion, are presented in the following table. Truck 40 °F 80 °F 1 859.7 831.5 783.3 803.5 3 872.8 876.3 4 955.3 852.9 824.7 810.2 897.4 860.5 7 953.3 838.5 806.9 757.0 9. 770.4 788.4 10 899.5 834.4 Send data to Excel Let u, represent the mean emission at 40 F and H=4-4- Can you conclude that the mean emissions are higher at 40 °F? Use the a=0.01 level of significance and the TI-84 Plus calculator to answer the following. Part: 0/4 Part 1 of 4 (a) State the null and alternate hypotheses. H;: This hypothesis test is a (Choose one) v test.

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.
