Question

For this week’s homework, we will revisit some old homework problems. But this time we’ll use R to solve them (you must use R to do problems 1 – 5). We’ll also collect a little data in class. 1) Find the following probabilities: a) Pr{Z < 4.3} b) Pr{Z > -1.69} c) Pr{-1.12 < Z < 1.12} d) Pr{-1.3 < Z < 0.98} e) Pr{Z < -1.12 or Z > 1.12} (you want the probability outside the range -2.67 to 2.67)

Answer:Step-by-step explanation:To answer these questions, we will make use of a z score tableSolving (a):Solving (b):First, we rewrite this using complement ruleFrom the z score table:So, we have:Solving (c)This is equivalent to:Use the z score tableSolving (d)This is equivalent toSolving (e)This is interpreted as:Apply complement rule
