Answer:
DNE
Step-by-step explanation:
The the given table, we have;
As x approaches -14 from the left, at x = -14.001, p(x) = 1.96
As x approaches -14 from the right, at x = -13.999, p(x) = 1.97
The value of p(x) when x = -14 is = Undefined, or is not definable, therefore, p(x) Does Not Exist (DNE) when x = -14, and we have;
Does Not Exist, DNE.
Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).
<h3>What is a z-distribution confidence interval?</h3>The confidence interval is:
In which:
In this problem, we have a 95% confidence level, hence, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
For this problem, the other parameters are:
Hence the bounds of the interval are:
The interval is: (17.5, 24.5).
