7.2.2.b Apply properties of operations to calculate with numbers in any form, convert between forms as appropriate, and assess the reasonableness of answers using mental computation and estimation strategies.
7.3.1.a.iii Use data from a random sample to draw inferences about a population with an unknown characteristic of interest.
7.3.1.a.iv Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions.
7.3.1.b Draw informal comparative inferences about two populations.
7.3.1.b.i Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.
7.3.1.b.ii Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.
7.3.2.b Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability.
7.4.2.d Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
