Answer ASAP: Probability and Statistics question
On average, 2.4 car accidents occur on certain highway each month (which is assumed to always have 30 days). Answer the following questions:
(a) What is the probability of having at least 1 accident on the highway next month?
Hint: Let LaTeX: XX denote the number of car accidents on the highway next month. What distribution does LaTeX: X X have?
(b) What is the probability that there will be no accident during the first 15 days of next month?
Hint: Let LaTeX: YYdenote the waiting time (in months) for the first accident that will occur on the highway next month. What does the question imply about LaTeX: YY?
(c) Given that there is no accident on the highway during the first 15 days of next month, what is the probability that there is no accident during the next 10 days of the month?
(d) Bonus question (5 extra points). Considering next year, let
LaTeX: ZZ denote the number of months in which there will be no car
accidents on the highway. What distribution does LaTeX: ZZ have? Be
sure to specify both the distribution name and parameter
value(s).

Answer ASAP: Probability and Statistics question
The desired percentage of SiO2 in a certain type of aluminous
cement is 5.50 or higher. Suppose that the percentage of SiO2 in a
specimen is normally distributed with unknown mean LaTeX: \muμμ but
known standard deviation LaTeX: \sigma=0.30σ = 0.30. To test
whether the true average percentage is actually less than 5.50 for
a particular production facility, we consider
LaTeX: H_0: \mu=5.50 \qquad \textrm{vs} \quad H_1: \mu<5.50H
0 : μ = 5.50 vs...

Answer ASAP: Probability and Statistics question
Assume that the helium porosity (in percentage) of coal samples
taken from any particular seam is normally distributed, but neither
the mean LaTeX: \muμ nor the variance LaTeX: \sigma^2σ 2 is known.
Suppose that we are given a sample of 25 specimens from the seam,
with average porosity 8.85 and standard deviation 0.75.
Answer the following questions:
(a) Construct a 98% confidence interval for LaTeX: \muμ. How
large is the margin of error?
(b)...

each month?
