Answer:
Confidence Interval: (0.44,1.00)
Step-by-step explanation:
We are given the following data set:
0.60, 0.74, 0.09, 0.89, 1.31, 0.51, 0.94
Formula:
where
are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 0.8809
![S.D = \sqrt{\frac{0.8809}{6}} = 0.383](https://tex.z-dn.net/?f=S.D%20%3D%20%5Csqrt%7B%5Cfrac%7B0.8809%7D%7B6%7D%7D%20%3D%200.383)
90% Confidence interval:
Putting the values, we get,
