The family error rate is the probability of obtaining a significant result for at least one of the t tests conducted, under the assumption that the null hypothesis is true. Use the tree diagram to determine the family error rate for two t tests, each conducted at a level of a=0.05. Show your work

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

inverse property is the answer

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
