An electric scale gives a reading equal to the true weight plus a random error that
is normally distributed with mean 0 and standard deviation s = .1 mg. suppose
that the results of five successive weighings of the same object are as follows: 3.142,
3.163, 3.155, 3.150, 3.141.
(a) determine a 95 percent confidence interval estimate of the true weight.
(b) determine a 99 percent confidence interval estimate of the true weight.

a) (3.1388,3.1616)

b) (3.1313,3.1691)  

Step-by-step explanation:

We are given the following data set:

3.142,  3.163, 3.155, 3.150, 3.141

Formula:

where are data points, is the mean and n is the number of observations.  

Sum of squares of differences =

a) 95% Confidence interval:

Putting the values, we get,

b) 99% Confidence interval:

Putting the values, we get,

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
