Transcribed Image Text:Suppose you take 4 air quality samples in parts per million: 19.6, 1.88, 12.7, 11.9.
Give a 90% confidence interval of the mean air quality? (Also, t(0.95,3) = 2.3534 and
t(0.90,4)= 1.5332)
(a) (3.45, 16.83)
(b) (0, 25)
(c) (2.93, 20.10)
(d) (5.22, 21.54)
(e) None of the above
Expert Solution

Step 1: Calculating the confidence interval we have
Data : 19.6, 1.88, 12.7, 11.9
Given
(t0.95,3)=2.3534
t0.90, 4=1.5332
At 90% confidence interval of the population mean air quality
Step by step
