Yo _________ (always) como pan en la mañana.

You are planning to go on a whale watching tour during your Hawaii vacation. In doing some research, you find that the number of whales seen on the tour follows a Poisson distribution with a mean of 3.0 whales. Based on this information, find the probability that you will see at least 3 whales on your tour. Hint: it might be faster and more accurate to find the complement and subtract from 1. However you do it, be sure your answer is accurate to 3 decimal places. Probability = [probability] Note: answer in decimal form and round to 3 decimal places.

A customer service center receives an average of 50 complaints per day, with a standard deviation of 12. Based on this information, and for a randomly selected day, answer the following questions. Round all probabilities to 3 decimal places: What is the probability of receiving less than 30 complaints? [p1] What is the probability of receiving more than 58 complaints? [p2] Would it be unusual to receive more than 58 complaints? (yes or no) [yesno] What is the probability of receiving between 40 and 60 complaints? [p3]

A mi hermana no le gusta la carne. A mí (neither) _____________.

Identify the following variable as being either continuous or discrete. The number of possible variations of this practice quiz.

Willy Wonka claims that 80% of all Gobbstopper candy it produces weighs more than 0.5 ounces. Suppose that 500 Gobbstoppers are selected at random from the production line. What are the lower and upper limits of what would be considered a “usual” number that meets Willy’s claim? Lower limit of “usual” = [lower] Upper limit of “usual” = [upper] Note: answer in decimal form and round to 1 decimal place

Find the mean and standard deviation for a binomial distribution with n = 52 and p = 0.28. Mean = [mean] Standard Deviation = [stdev] (Note: answer in decimal form, rounding the mean to 1 decimal place, and the standard deviation to 2 decimal places)

A customer service center receives an average of 60 complaints per day, with a standard deviation of 15. Based on this information, and for a randomly selected day, answer the following questions. For what number of complaints (x) is the probability 20% that there are less than that number of complaints? (round answer to 1 decimal) [x1] For what number of complaints (x) is the probability 40% that there are more than that number of complaints? (round answer to 1 decimal) [x2]

If z is a standard normal variable (normally distributed), find the probability that z is less than 1.00. Probability = [probability] Note: answer in decimal form and round to 3 decimal places.
