In a small island, earthquakes occur two and a half times per year on average. Assume the number of the earthquakes follows from a Poisson distribution. What is the probability that there are at most 3 earthquakes in a two-year period?

Among 2000 computer chips, 600 are defective. Randomly select 8 chips without replacement. What is the probability of getting 2 defective chips?  You can use the method of binomial approximation to hypergeometric distribution.    

Which of the following is true regarding the best predictor for having an episode of low back pain?

Which Holland personality type is typically described as persuasive, energetic, and interested in leadership? Chapter 9: Personality and cultural values    

Which Holland type is most associated with creativity, self-expression, and originality? Chapter 9: Personality and cultural values

A researcher noticed that, for streams along the East Coast, the amount of money spent on restoration and the number of distinct fish populations present appeared to have a negative correlation. To investigate this observed association, how should the researcher begin his research?

  (25 pts) Use the 700 millibar map above to answer the questions that follow. Temperature is portrayed by the dashed lines while geopotential height is given by solid lines. Do you see an area of confluence on this map? Confluence refers to along-trajectory convergence in the field.  If so, which state(s) are experiencing confluence? (5 points) What type of temperature advection is occurring over Illinois at this time? Is that advection strong or weak? Explain your reasoning (5 points) Looking northeastward, what is the predominant geostrophic wind direction over New York state? Based on the conditions you see on the weather map, speculate as to what the geostrophic wind direction at 500 millibars would be in New York at the same time. (10 points) Based on the 700 mb pattern in height and temperature, indicate the rough trajectory of the polar jet stream by listing the states it would be passing over. (5 points)

(20 points) Consider the idealized flow example below. In the image, solid lines are 500 millibar geopotential heights, while dashed lines are 700 millibar geopotential heights.  Answer the questions that follow. Ensure that your answer to each part is clearly labeled. (10 points) Which point is warmest? Which is coldest? Explain. (5 points) What is the geostrophic wind direction at both levels at point C? Determine the direction the thermal wind vector would be pointing at C. Recall that:
