The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t)=3+70t-16t2. the average rate of change in h(t) between t = 1 second and t = 3 second is 6. what does the average rate of change tell you about the rocket? a.)the rocket is traveling six times as fast when t = 3 than it is when t = 1. b.)the rocket is at a greater height when t = 3 than it is when t = 1. c.)the rocket is 6 feet higher above the ground when t = 3 than it is when t = 1. d.)the rocket is traveling at a constant rate of 6 feet per second between t = 1 and t = 3.

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
