Why might the statistics calculated by examining a sample not accurately represent a population? Bias can be introduced when selecting the samples to be measured. Statistics are used to describe a sample but are not a proxy for population parameters. Sample statistics are measured in animals, whereas population parameters are measured in plants. If the sample size is very large, the sample statistics are less likely to approximate the population parameters.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
