(g)If a fawn weighs 14 kilograms, would you say it is an unusually small animal? Explain usingzvalues and the figure above.
Yes. This weight is 3.57 standard deviations below the mean; 14 kg is an unusually low weight for a fawn.
Yes. This weight is 1.78 standard deviations below the mean; 14 kg is an unusually low weight for a fawn.
No. This weight is 3.57 standard deviations below the mean; 14 kg is a normal weight for a fawn.
No. This weight is 3.57 standard deviations above the mean; 14 kg is an unusually high weight for a fawn.
No. This weight is 1.78 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 thezvalue for the weight of the fawn will be close to 0,2, or 3? Explain.
It would have azof 0.
It would have a large positivez, such as 3.
It would have a negativez, such as2.
