The \( 35^{\text{th}} \) percentile is between the first quartile (Q1) and the median. The \( 80^{\text{th}} \) percentile is between the median and the third quartile (Q3).

Solución

To determine the location of the \( 35^{\text{th}} \) and \( 80^{\text{th}} \) percentiles using the five-number summary, we first need to understand what the five-number summary consists of: 1. Minimum 2. First Quartile (Q1, \( 25^{\text{th}} \) percentile) 3. Median (Q2, \( 50^{\text{th}} \) percentile) 4. Third Quartile (Q3, \( 75^{\text{th}} \) percentile) 5. Maximum ### Step 1: Identify the Five-Number Summary Assuming we have the five-number summary values, let's denote them as follows: - Minimum = \( a \) - Q1 = \( b \) - Median = \( c \) - Q3 = \( d \) - Maximum = \( e \) ### Step 2: Determine the Location of the \( 35^{\text{th}} \) Percentile The \( 35^{\text{th}} \) percentile is between the first quartile (Q1) and the median (Q2). Since Q1 corresponds to the \( 25^{\text{th}} \) percentile and the median corresponds to the \( 50^{\text{th}} \) percentile, we can conclude that: - The \( 35^{\text{th}} \) percentile is between \( b \) (Q1) and \( c \) (Median). ### Step 3: Determine the Location of the \( 80^{\text{th}} \) Percentile The \( 80^{\text{th}} \) percentile is between the median (Q2) and the third quartile (Q3). Since the median corresponds to the \( 50^{\text{th}} \) percentile and Q3 corresponds to the \( 75^{\text{th}} \) percentile, we can conclude that: - The \( 80^{\text{th}} \) percentile is between \( c \) (Median) and \( d \) (Q3). ### Conclusion - The location of the \( 35^{\text{th}} \) percentile is between \( b \) and \( c \). - The location of the \( 80^{\text{th}} \) percentile is between \( c \) and \( d \). If you have specific values for the five-number summary, please provide them for a more precise conclusion.

Beyond the Answer

To determine the locations of the \( 35^{\text{th}} \) and \( 80^{\text{th}} \) percentiles using the five-number summary—which includes the minimum, first quartile (Q1), median, third quartile (Q3), and maximum—you can interpolate between these values. The \( 35^{\text{th}} \) percentile will be positioned between the first quartile (Q1) and the median, while the \( 80^{\text{th}} \) percentile will be situated between the third quartile (Q3) and the maximum on a typical scale. For practical application, knowing where percentiles fall can significantly enhance data-driven decisions in various fields, like education, where understanding student performance percentiles can help tailor instructional strategies. Similarly, businesses often use these insights for market segmentation, identifying where their sales data fit within market expectations to refine offerings and enhance competitiveness.
