Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 800

grams while babies born after a gestation period of 40 weeks have a mean weight of 2800 grams and a standard deviation of 425 grams. If a 33​-week gestation period baby weighs 2600 grams and a 41​-week gestation period baby weighs 2900 ​grams, find the corresponding​ z-scores. Which baby weighs more relative to the gestation​ period?

Answer:

Babies of 33 week weighs relatively less than the babies of 41 week.

Explanation:

Z score is determined by

=\frac{x-u}{SD}

A) For 33 Week baby

Given

Mean = 2500

SD= 800

x=2600

Z score is

\frac{2600-2500}{800} \\= 0.125

B) For 41 Week baby

Given

Mean = 2800

SD= 425

x=2900

Z score is

\frac{2900-2800}{425} \\= 0.235

The z score depicts that the baby of 33 week or 41 week weighs more than the normal babies of same age group.

Thus, babies of 33 week weighs relatively less than the babies of 41 week.

Answer:

The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.

Explanation:

The aniridia allele in females has to be in the XAXA or XAXa form to be expressed but in males, can be expressed when genotype is XAY.

Migraine headaches allele in females has to be in the XMXM or XMXm form to be expressed but in males, can be expressed when genotype is XMY.

A man with normal vision and without migraines (XaY/XmY) had a father who had aniridia (XAY).

The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
