Consider X. It is a normally distributed random variable, with its mean being equal to 75 and its standard deviation being equal to 25. We pick up a randomly selected observation from X, and we call it X. As it happens, X1 is equal to 82.5. What is the z-score for X1? OZ1--0.7 OZ1-0.5 O Z1--0.3 O 21-03 O21--0.5 O21-07 1 pt. Question 2 1 pts There is also another randomly-selected observation from X, denoted by X2. We do not know its value. But we happen to know its z-score: Z--2.45. What is the value for X2? OX2-1243 OX2-21.34 OX2-13.75 OX2-5125 O X2-15.52 OX2-31.57 U Relying on what we did in our Excel demonstration, we can be confident to say that z-scores are rarely greater than Hint: In Excel, you may use a command called -COUNTIF to count the number of occurrences associated with the z-scores below. Here is the syntax for the aforementioned command. 3 O2 01 +2 0 +1 +3 Question 4 1 pts Relying on what we did in our Excel demonstration, we can be confident to say that z-scores are rarely less than Hint: In Excel, you may use a command called -COUNTIF to count the number of occurrences associated with the z-scores below. Here is the syntax for the aforementioned command. 01 03 +2 10.+3 02
