If a set of observations is normally distributed, what percent of these differ from the mean by (a) more than 2.20? (b) less than 0.32g? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table.
Use Table A (Standard Normal Distribution) to find the proportion of observations that satisfies each of the following statements. In each case, shade the area under the curve that is the answer to the question. The table chart below is the one that needs to be looked at to find the proportion of observations that satisfies each of the following statements. The table chart along with the questions that needs to be correctly answered and shaded are below. This deals with Measures of Variations.
