Document Summary
Immense support for a hypothesis=theory- no doubts about what is discovered so far. Null hypothesis (h0) and alternative hypothesis (ha) What is correlation: can occur as positive correlation-one variable increases the other increases, negative correlation-one variable increases the other decreases, no correlation-no pattern.

Dna is the basis of heredity; double helix, sides of the ladder are made up of deoxyribose (a sugar) and phosphates-rungs are nucleotides- a t c g (adenine, thymine, guanine, cyanine)
