given
Let DE be a line passing through Band parallel to AC. definition of parallel lines
23 25 and 2124
v
m_1 = m 24 and m3 = m25
m24+ m2 + m25 = 180°
angle addition and definition of a straight line
m2 1 + m2 2 + m23 = 180°
substitution

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
