Question
Answer:
Answer:The 5-number summary refers to:Minimum = 16First Quartile (Q1) = 46.5Median = 78Third Quartile (Q3) = 82Maximum = 94See the explanation section for detailsStep-by-step explanation:The 5-number summary refers to:Minimum = 16First Quartile (Q1) = 46.5Median = 78Third Quartile (Q3) = 82Maximum = 941. Minimum is 16. Since the number is already arranged in ascending order.2. First Quartile is defined as the median of the lower half. [tex]Q1 = \frac{46 + 47}{2} = 46.5[/tex]46 and 47 are the median of the first half of the score, that is 15th and 16th score.3. Median is the sum of the 30th and 31th score divide by two, which is 78 and 78. Median = [tex]\frac{78 + 78}{2} = \frac{156}{2} = 78[/tex]4. Third quartile is define as the median of the upper half. [tex]Q3 = \frac{82 + 82}{2} = 82[/tex]82 and 82 are the median of the upper half of the score, that is 45th and 46th score.5. Maximum is 94.
