Tim is investigating the relationship between the number of years since a tree was planted and the height of the tree in feet. his data are shown in the table. years since tree was planted vs. height of tree years since tree was planted, x height of tree in feet, y 2 17 3 25 5 42 6 47 7 54 9 69 using a regression calculator, what is a good prediction for the height of the tree when it is 100 years old?

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
