Xis a uniform random variable with limits [-4,8]. given a condition that b={|x| ≤ 2} a. find the conditional pdf �: |< (�) and plot both the original and this conditional pdf. b. find the conditional expected value e[x|b]? c. what is the conditional variance, var[x|b].

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.
