Determine the appropriate inference method for each setting below. a) A biologist believes the offspring of certain gupples will have 25% red tails, 50% blue tails, and
25% orange tails. She test her theory with a sample of 23 offspring.
b) Are drivers in Florida better than in California? A survey asks randomly selected drivers from
each state whether or not they have been involved in a car accident in the last 5 years.
c) A new variety of orange is developed, and a sample of oranges is tested to see if their vitamin C
content is different than the 70 milligrams found in regular oranges.
d) A math teacher wants to estimate how long his students study each night. He asks ten randomly
selected students to record the number of minutes they study each night for a week.
e) Can the length of a giant sea clam be used to predict its shell thickness? A scatterplot of the
lengths and shell thickness of 14 giant sea cams shows a roughly linear relationship,

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
