I'm a passionate educator with a focus on Statistics, holding a degree from Cedarville University. My commitment to fostering a deep understanding of the subject drives me to help students grasp complex concepts effortlessly. With a foundation rooted in academia, I bring practical insights to the virtual classroom. Let's embark on a journey of learning and unravel the mysteries of statistics together!


  • Suppose that you take a 20 question multiple-choice quiz by guessing. Each question has exactly one correct answer of the four alternatives given. What is the probability of getting all 20 questions incorrectly?
  • Box and whisker plot? The data set 5,6,7,8,9,9,9,10,12,14,17,17,18,19,19 represents the number of hours spent on the internet in a week by students in a mathematics class. Construct a box and whisker plot that represents the data. Does anyone know how to
  • What information can you represent with a box and whisker plot?
  • Among the contestants in a competition are 42 women and 28 men. If 5 winners are randomly selected, what is the probability that they are all men?
  • In a one-way ANOVA, if the test is conducted and the null hypothesis is rejected, what does this indicate?
  • Suppose that P(A) = 0.3 and P(B) = 0.25 and P(A ∩ B) = 0.1. What is P(B | A(complement))?
  • How do you calculate marginal, joint, and conditional probabilities from a two-way table?
  • How does the normal distribution differ form the Poisson distribution?
  • What is the mathematical difference between the probability density functions of a normal distribution and a standard normal distribution?
  • Assume that the weights of quarters are normally distributed with a mean of 5.67 g and a standard deviation 0.070 g. A vending machine will only accept coins weighing between 5.48 g and 5.82 g. What percentage of legal quarters will be rejected?
  • What is the total number of possible 5-letter arrangements of the letters D, I, S, C, and O, if each letter is used only once in each arrangement?
  • Two dice are rolled together and X is the highest score minus the lowest score of the dice. What are the possible values of X?

  • A fair six sided die is rolled four times in a row. What is the probability that die will come up six at least once?
  • The freshman class has 160 students. Each freshman must write three reports from a list of 12 novels that the teacher has assigned them to read. How many different combinations of novels can a freshman student choose to write reports on?
  • What is the mean and standard deviation of 5, 10, 12, 15, 20?
  • The letters in the word "baseball" are placed in a bag. If a letter is picked at random, what is the probability that an "a" will be selected?
  • How many distinct four-digit numbers contain the digits 1, 2, 3, and 4 without repetition, if the digit 2 is always immediately followed by the digit 3?
  • If a distribution has a mean of 100 and a standard deviation of 15, what value would be +2 standard deviations from the mean?
  • A trait has two alleles, represented by #p# and #q#. If #p=0.89#, what is #q#?
