(g) If a fawn weighs 14 kilograms, would you say it is an unusually small animal? Explain using z values and the figure above.

Yes. This weight is 3.14 standard deviations below the mean; 14 kg is an unusually low weight for a fawn.

Yes. This weight is 1.57 standard deviations below the mean; 14 kg is an unusually low weight for a fawn.

No. This weight is 3.14 standard deviations below the mean; 14 kg is a normal weight for a fawn.

No. This weight is 3.14 standard deviations above the mean; 14 kg is an unusually high weight for a fawn.

No. This weight is 1.57 standard deviations above the mean; 14 kg is an unusually high weight for a fawn.

(h) If a fawn is unusually large, would you say that the z value for the weight of the fawn will be close to 0, −2, or 3? Explain.

It would have a z of 0.

It would have a large positive z, such as 3.

It would have a negative z, such as −2.
