Fawns between 1 and 5 months old have a body weight that is approximately normally distributed with mean ? = 26.2 kilograms and standard deviation ? = 3.7 kilograms. Let x be the weight of a fawn in kilograms. Convert the following z intervals to x intervals. (Round your answers to one decimal place.) (a) −2.17 < z < x(b) z < 1.28x < (c) −1.99 < z < 1.44 < x < (d) If a fawn weighs 14 kilograms, would you say it is an unusually small animal? Explain using z values and the figure above. a. Yes. This weight is 3.30 standard deviations below the mean; 14 kg is an unusually low weight for a fawn. b. Yes. This weight is 1.65 standard deviations below the mean; 14 kg is an unusually low weight for a fawn. c. No. This weight is 3.30 standard deviations below the mean; 14 kg is a normal weight for a fawn. d. No. This weight is 3.30 standard deviations above the mean; 14 kg is an unusually high weight for a fawn. e. No. This weight is…
