Test the hypothesis that the downtown police officers have a higher lead exposure than the group in the previous study. (Use a significance level of 0.05.) Calculate the test statistic. (Round your answer to two decimal places.) t = 1B. What can be said about the P-value for the test? A. p-value > 0.100 B. 0.050 < p-value < 0.100 C. 0.025 < p-value < 0.050 D. 0.010 < p-value < 0.025 E. 0.005 < p-value < 0.010 F. p-value < 0.005

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.

F. p-value < 0.005
Transcribed Image Text:Researchers interested in lead exposure due to car exhaust sampled the blood of 52 police officers subjected to constant inhalation of automobile exhaust fumes while working traffic
enforcement in a primarily urban environment. The blood samples of these officers had an average lead concentration of 122.38 µg/l and a SD of 39.71 µg/I; a previous study of
individuals from a nearby suburb, with no history of exposure, found an average blood level concentration of 35 µg/l.
