Juries should have the same racial distribution as the surrounding communities. according to the u. s. census bureau, 18% of residents in minneapolis, minnesota, are african americans. suppose a local court will randomly sample 100 state residents and will then observe the proportion in the sample who are african american. how likely is the resulting sample proportion to be between 0.066 and 0.294 (i. e., 6.6% to 29.4% african american)? there is roughly a 95% chance that the resulting sample proportion will be between 0.066 and 0.294 of the true proportion. there is roughly a 99.7% chance that the resulting sample proportion will be between 0.066 and 0.294 of the true proportion. there is roughly a 68% chance that the resulting sample proportion will be between 0.066 and 0.294 of the true proportion. it is certain that the resulting sample proportion will be between 0.066 and 0.294 of the true proportion.

step-by-step explanation:

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.
