Question
Fawns between 1 and 5 months old have a body weight that is approximately
Convert the following z intervals to x intervals. (Round your answers to one decimal place.)
(a) −2.17 < z
< x
(b) z < 1.28
x <
(c) −1.99 < z < 1.44
< x <
< x
(b) z < 1.28
x <
(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 1.65 standard deviations above the mean; 14 kg is an unusually high weight for a fawn.
(e) 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.
(e) 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.
a. It would have a negative z, such as −2.
b. It would have a z of 0.
c. It would have a large positive z, such as 3.
