Lefties find the sample size needed to estimate the percentage of california residents who are left-handed. use a margin of error of three percentage points, and use a confidence level of 99%. a. assume that p and are unknown. b. assume that based on prior studies, about 10% of californians are left-handed. c. how do the results from part (a) and (b) change if the entire united states is used instead of california?

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.
