According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.35. Suppose a random sample of 108 traffic fatalities in a certain region results in 50 that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the α=0.01 level of significance?
Because np 0 (1−p0) = _______ ________10, the sample size is ___________5% of the population size, and the sample ____________the requirements for testing the hypothesis ___________satisfied.
(Round to one decimal placeas needed.)

According to an international aviation firm, fatal accidents
occur in just around one in every five million flights. With about
100,000 flights per 24 hour day worldwide, this means fatal
accidents happen at a rate of 1 per 50 days. This translates to an
average of 0.6 accidents per month. Assume that the number of fatal
air accidents worldwide follows a Poisson distribution with λ=0.6
per month.
Compute the probability that no fatal air accident will happen
anywhere in the...

At a certain black spot, the number of traffic accidents per
year follows a Po 10,000)-distribution. The number of deaths per
accident follows a Po(0.1)-distribution, and the number of
casualties per accidents follows a Po(2)-distribution. The
correlation coefficient between the number of casualties and the
number of deaths per accidents is 0.5. Compute the expectation and
variance of the total number of deaths and casualties during a
year.
