Choose the correct description of the graph of the compound inequality: x − 3 < −9 or x + 5 greater than or equal to 12 a number line with a closed circle on −6, shading to the left, and an open circle on 7, shading to the right a number line with an open circle on −6, a closed circle on 7, and shading in between a number line with an open circle on −6, shading to the left, and a closed circle on 7, shading to the right a number line with a closed circle on −6, an open circle on 7, and shading in between

People end up tossing 12% of what they buy at the grocery store. 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. a. calculate the mean and the standard error for the sample proportion p. b. describe the sampling distribution of p in part a. draw a graph of this probability distribution with its mean and standard deviation. what is the probability that your survey will provide a sample proportion more than 15%? c. d. population proportion? what is the probability that your survey will provide a sample proportion within + 0.03 of the
