As a general rule, the sampling distribution of the sample proportions can be approximated by a normal probability distribution whenever

a)np greater than or equal to 5
b) n(1-p) greater than or equal to 5
c) n greater than or equal to 30
d) both a and b are true
a continuous random variable is uniformly distributed between a and b. the probability density function between a and b is
a) zero.
b) (a - b).
c) (b - a).
d) 1/(b - a).

a population has a mean of 84 and a standard deviation of 12. a sample of 36 observations will be taken. the probability that the sample mean will be between 80.54 and 88.9 is

a) 0.0347.
b) 0.7200.
c) 0.9511.
d) none of the alternative answers is correct.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
