Q.3.1 - The Practice of Statistics for AP

Question

The figure below shows Minitab output from a significance test and confidence interval for the restaurant worker data in the previous Check Your Understanding (page 558). Explain how the confidence interval is consistent with but gives more information than, the test.

Step-by-Step Solution

Answer

The confidence interval is consistent but gives more information than the test as more data has been given by the certainty stretch since it is giving the reach rather than speculation.

Step 1: Introduction

Confidence interval is the mean of your gauge in addition to and short the variety in that gauge. This is the scope of values you anticipate that your gauge should fall between assuming you re-try your test, inside a specific degree of certainty. Certainty, in measurements, is one more method for depicting likelihood.

Step 2: Explanation

It is realized that the invalid speculation has not been dismissed and the certainty span affirms this outcome on the grounds that the extent is lying somewhere in the range of $0.589$ and $0.771$. Anyway, more data has been given by the certainty span since it is giving the reach rather than theory just infer that the extent is equivalent to $0.75$
