Researchers collected information on the body parts of a new species of frog. The thumb length for the female frog has a mean of 6.97 mm and a sta a. Find the standardized version of x. b. Determine and interpret the z-scores for thumb lengths of 7.5 mm and 6.3 mm. Round your answers to two decimal places. a. Find the standardized version of x. x - 6.97 0.52 (Do not simplify. Use integers or decimals for any numbers in the expression. Do not round.) b. Determine and interpret the z-scores for thumb lengths of 7.5 mm and 6.3 mm. Round your answers to two decimal places. Determine and interpret the z-score for a thumb length of 7.5 mm. The z-score for a thumb length of 7.5 is This is standard deviations the mean thumb length. (Round to two decimal places as needed.) Determine and interpret the z-score for a thumb length of 6.3 mm. The z-score for a thumb length of 6.3 is This is standard deviations the mean thumb length. (Round to two decimal places as needed.)
