Question

a sample of sand is taken at random from the shore of a lake. the table shows the estimated proportions of different materials present in the sample, with a margin of error of 0.07. based on these estimates and margin of error, which of the following is the most appropriate conclusion about the proportions of different materials present in the sand? garnet: 0.01, basalt: 0.19, organic matter: 0.12, quartz: 0.68. the proportion of quartz will be greater than 0.61. the proportion of garnet will be greater than 0. the proportion of garnet will be lower than the proportion of organic matter. the proportion of organic matter will be lower than the proportion of basalt.

Explanation:

Step1: Analizar proporciones

La proporción de cuarzo es 0.68.

Step2: Comparar con valores dados

0.68 > 0.61.

Answer:

The proportion of quartz will be greater than 0.61
