Questions 1 – 2 refer to the following: Below is the probability distribution function for the number of high school years that students at a local high school play on a sports team.
According to the 2000 United States Census, 12.3% of the population is Black or African American. The probability that a randomly selected U. S. resident is NOT Black or African American is:
Assume the statistics final is a multiple choice test with 40 questions. Each question has four choices with one correct answer per question. If you were to randomly guess on each of the questions, what is the probability of getting exactly the expected number of correct answers?
In Fall 1999, students in one Math 10 section determined that the length of movies at the cinema was normally distributed with a mean of 148 minutes and a standard deviation of 19 minutes.
Find the third quartile and interpret it.
75 minutes; Three-fourths of the movie lengths fall below 75 minutes.
160.8 minutes; Three-fourths of the movie lengths fall below 160.8 minutes.
160.8; Three-fourths of the movies last 160.8 minutes.
75 minutes; Three-fourths of the movies last 75 minutes.
The graph showing the age of getting a driver’s license in California starts and peaks at age 16, and decreases from there. This shape most closely resembles what type of distribution?
Use the following information for questions 9 and 10. The amount of time that a randomly chosen 6th grade student spends on homework per week is uniformly distributed from 30 to 120 minutes.
What is the probability that a randomly chosen 6th grade student spends at least 60 minutes per week on homework knowing that he/she will spend at most 80 minutes per week on homework?
Use the following information for questions 11 and 12. The length of time a randomly chosen 9-year old child spends playing video games per day is approximately exponentially distributed with a mean equal to 2 hours.
Find the probability that a randomly chosen 9-year old will play video games at most 3 hours.

A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
