Among 21802180 passenger cars in a particular region, 246246 had only rear license plates. among 302302 commercial trucks, had only rear license plates. a reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. use a 0.100.10 significance level to test that hypothesis.

There is statistical evidence at 1% significance level to support that  commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.

Step-by-step explanation:

Given that among 2180 passenger cars in a particular region, 246 had only rear license plates. Among 302 commercial trucks, 44 had only rear license plates.

Total                    2180      302       2482

X                             246       44         290

(left tailed test at 1% significance level)

Std error of p =

Test statistic Z = p differnce/std error =

p value <0.0001

Since p is less than 1% we reject null hypothesis

There is statistical evidence at 1% significance level to support that  commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.
