Rule= (x,y) is now (y,x) so coordinates of (5,4) now would be (4,5). this is the rule for y=x problems so you take the coordinates and flip them for every point.
Answer:
And the confidence interval for the true mean would be (1.10; 3.40)
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n=100 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The Confidence interval is 0.9544 or 95.44%, the significance would be
and
, and the critical value for this case would be
Replacing we got:
And the confidence interval for the true mean would be (1.10; 3.40)
