* + 5 Suppose f(z) 2? – 4 a. Notice that f(3) = 1.6. What does this tell us about the numerator and the denominator of f? When z = 3, the value of -0.4 |* is -0.4 ]* times as large as the value of z? – 4. (Hint: In this case, the first answer should be an expression in terms of z, and the second answer should be a number.) b. Use function notation to represent the answer to the question, "when z = 7.3, z + 5 is how many times as large as z² – 4?". |* Preview

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
