Question
You are expected to do this question using the 68-95-99.7 rule by hand, that is, without the aid of RStudio. Suppose that Z is the standard normal distribution. a) Use the 68 - 95 - 99.7 rule to compute the following probabilities. Note that the answers should be entered as decimals, not percentages. i) P(−1 < Z < 1) = ii) P(Z < − 1) = Number Number (Enter the exact decimal value according to the 68-95-99.7 rule) (Enter the exact decimal value according to the 68-95-99.7 rule) iii) P(−3 < Z < −1) = Number b) Using the 68 - 95 - 99.7 rule, find the value of z such that P(Z ≤ z) = 0.9985. z = Number (Enter the exact value according to the 68-95-99.7 rule) (Enter the exact decimal value according to the 68-95-99.7 rule)
