Solution Steps

Step 1: Analyze the sampling method in question 4
  • The teacher selects rows two and five and includes all students in those rows. This means she is selecting entire groups (rows) rather than individual students.
  • This method is known as Cluster Random Sampling, where the population is divided into clusters (rows in this case), and entire clusters are randomly selected for inclusion in the sample.
Step 2: Analyze the sampling method in question 5
  • The librarian records data for every fourth patron who checks out books. This involves selecting samples at regular intervals (every fourth patron).
  • This method is known as Systematic Random Sampling, where a starting point is chosen randomly, and then every \( k \)-th element is selected from the population.
Step 3: Match the sampling methods to the options
  • For question 4, the correct answer is C Cluster Random Sample.
  • For question 5, the correct answer is B Systematic Random Sample.

Final Answer

For question 4: \(\boxed{C}\)
For question 5: \(\boxed{B}\)

The average final exam score for the statistics course is 78. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is higher. The final exam scores for the 13 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 100,100,74,78,69,65,70,71,95,96,99,84,76 What can be concluded at the α=0.10 level of significance? a.
