Open Question: Why do people say homosexuality is normal?

Open Question: Why do people say homosexuality is normal?

Just look at the biological purpose of sex. Male > Female = New generation of human race. But homosexuals can't produce kids, so their sexual behavior violates the natural function of sex. It is really quite simple.

What is the purpose of a Penis? How does it relate to the Vagina and Uterus? These organs are designed for each other for a very specific purpose, to produce new humans.

What is the function of an Anus? It is for the dumping of bodily waste, and in no way does it relate to the natural function of the Penis.

Maybe it is naturally occurring, but that doesn't mean homosexuality is normal or right. Autism and Down Syndrome are also naturally occurring, and these are recognized as mental disorders.

Open Question: Statistical Methods (proportion, normal distribution)?

Open Question: Statistical Methods (proportion, normal distribution)?

Protein shakes can act as a protein supplement such as for athletes that undergo rigorous strength training. Suppose the protein content of packets of a particular brand of protein shakes has population mean 20g and population standard deviation 0.9g. Assume that the protein content of packets follows very approximately a Normal distribution.

a) What proportion of packets will have a protein content of less than 19.5g?

b) What proportion of packets will have a protein content between 19g and 21g?

c) Now suppose a simple random sample of 12 packets is taken. What is the probability that the average protein content of this sample is above 20.2g?
