The professor teaching a large introductory class gives a final exam that has alternate forms, A, B, and C. A student taking the exam using Form B is upset because she claims that Form B is much harder than Forms A and C. Discuss how percentile point data might be useful to determine if the student is correct
Answer
We know that the percentile point data provides us information about the data set and their position or rank in the entire data set.
Suppose, if a data value has percentile point data of 75, then this means that 75% of all the values are below the given data value in the entire data set
So, we can use the percentile point data in order to check the position of student A in comparison with student B and C, this will helps us know whether the student A is making a false statement or true statement.

The professor of a introductory calculus class has stated that, historically, the distribution of final exam grades in the course resemble a Normal distribution with a mean final exam mark of μ=63μ=63% and a standard deviation of σ=9σ=9%. If using/finding zz-values, use three decimals. (a) What is the probability that a random chosen final exam mark in this course will be at least 73%? Answer to four decimals. (b) In order to pass this course, a student must have a...

A student gathers student final exam scores for 3 different professors teaching the same class. She uses ANOVA to test the claim that the 3 sections have the same average score. Her p-value is very close to o. What conclusion should she draw? Select one: a. The test is significant and it appears that the 3 samples have the same final exam averages b. The test is not significant and it appears that the 3 samples have the same final...
A set of final examination grades in an introductory statistics course is normally distributed, with a mean of 73 and a standard deviation of 7. Complete parts (a) through (d). a. What is the probability that a student scored below 86 on this exam? (Round to four decimal places as needed.) b. What is the probability that a student scored between 66 and 93? (Round to four decimal places as needed.) c. The probability is 55% that a student taking...
stats Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor...

Exam grades: Scores on a statistics final in a large class were normally distributed with a mean of 71 and a standard deviation of 8. Use the T1-84 PLUS calculator to answer the following. Round the answers to at least two decimals. (a) Find the 47 percentile of the scores (b) Find the 65 percentile of the scores. (c) The instructor wants to give an A to the students whose scores were in the top 12% of the class. What...
