People end up tossing 12% of what they buy at the grocery store (reader's digest, march 2009). assume this is the true population proportion and that you plan to take a sample survey of 540 grocery shoppers to further investigate their behavior. use z-table. show the sampling distribution of ( ), the proportion of groceries thrown out by your sample respondents (to 4 decimals). p = standard error of the proportion σ( ) = what is the probability that your survey will provide a sample proportion within ±.03 of the population proportion (to 4 decimals)? what is the probability that your survey will provide a sample proportion within ±.015 of the population proportion (to 4 decimals)?

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

answer: the answer to this problem is 2x and 2-x both have x as well as 2

step-by-step explanation: first you have to see what is the closest thing they have similar second you note it example 4x and 4+x they both have x and 4

i may be incorrect but i believe that her first error was in step one when she multiplyed her equation by 1/4 when she should have divided it by 1/4
