33. List at least four different weather phenomena that would be mentioned in an urgent (UUA) PIREP, including any altitudes or ranges where these phenomena must occur.

1. Explain when FM and TEMPO groups are used in a TAF, including the three conditions needed for a TEMPO to be included.

35. List at least four weather scenarios where a G-AIRMET would be issued. Include any thresholds and units in your scenarios for full credit.

18. Thunderstorm motion is a function of which two effects? A. Propagation and deviation B. Deviation and advection C. Propagation and advection  

Why is random sampling critical for the validity of sampling distributions?

If a normal population has µ=500 and σ=40, what is the mean and standard deviation of the sampling distribution of the mean based on a sample size n=4 and n=16.  

A company operates two plants for manufacturing motorcycles. The first plant produces 70% of the motorcycles, while the remaining 30% are produced at the second plant. Quality assessments reveal that 80% of motorcycles from the first plant meet the standard quality, whereas 90% from the second plant are of standard quality. If a motorcycle is selected at random and found to be of standard quality, determine the probability that it was manufactured at the second plant. The following events can defined from the problem statement Event A: The motorcycle is manufactured at the first plant.Event B: The motorcycle is manufactured at the second plant.Event C: The motorcycle is of standard quality. (1) Write the probabilities associated for each of the following events. (3pt)P(A)P(B)P(C|A)P(C|B) (2) Write the formulation for calculating P(C) and calculate the probability that a randomly picked motorcycle is of standard quality. (3pt) (3) State the Baye’s theorem formula for determining the probability that the motorcycle selected at random is from the second plant given that it is found to be of standard quality P(B|C) and calculate P(B|C). (4pts)

Why might the sample standard deviation be used instead of the population standard deviation?

Which of the following best describes a point estimate?

What would be an effect of using nonrandom sampling methods on the conclusions drawn from the sampling distribution?
