(27)Two-hundred students took a statistics class. Their professor creatively decided to give each of them their Z-score instead of their grade. Rachel got her Z-score of -0.2. She was wondering how well she did on the exam.a. It was very good, much better than almost all of the other studentsb. It was so-so, but still better than half of the students.c. It was not that good, but not at the bottom of the distributiond. It was very bad and she needs to work much harder next time24. (28) A researcher collected some data and they form a normal distribution with a mean of zero. What’s the probability of getting a positive number from this distribution?a. 25%b. 50%c. 75%d. We need to calculate the standard deviation and then decide.25. (29) Which of the following description of distribution is correct?a. A Binomial distribution is a probability distribution for independent events for which there are only two possible outcomesb. You cannot use the normal distribution to approximate the binomial distributionc. Normal distributions cannot differ in their means and in their standard deviations.d. Standard normal distributions can differ in their means and in their standard deviations.26. (30) A toy factory makes 5,000 teddy bears per day.
