The \( 2^{\text {nd }} \) class in a grouped frequency distribution is \( 8 \leq x<14 \). The \( 5^{\text {th }} \) class is:

1. The width of the class interval is calculated as \[ \text{width} = 14 - 8 = 6. \] 2. Since the second class is \(8 \leq x < 14\), the first class must be immediately preceding it with the same width, namely, \[ 8 - 6 = 2. \] Thus, the first class is \[ 2 \leq x < 8. \] 3. Knowing that the class width is 6, each subsequent class increases its lower and upper limits by 6. Therefore: - The third class: \[ 14 \leq x < 20, \] - The fourth class: \[ 20 \leq x < 26, \] - The fifth class: \[ 26 \leq x < 32. \] The \(5^{\text{th}}\) class in the grouped frequency distribution is \[ 26 \leq x < 32. \]
