With three randomly selected households are surveyed. the numbers of people in the households are 1, 4 and 10. assume that the samples of size n=2 are randomly selected with replacement from the population of 1, 4 and 10. listed below are the nine different samples: 1,1 1,4 1,10 4,1 4,4 4,10 10,1 10,4 10,10 find the variance of each of the nine samples: (find s^2 and probability) s^ 2 is 4.5, 0, or 1 ? whats the probability? s^2 is 9, 4.5, 2.3 ? whats the probability? s^2 is 18, 72, or 9? whats the probability? s^2 is 20.3, 81 or 40.5? whats the probability?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
