Question 375517
  <pre><font size = 3 color = "indigo"><b>
Hi,
*Note: Formula for the test statistic is {{{t = (x - mu)/(sigma/sqrt(n))}}}
In this case n = 5
Entering the Data into an Excel worksheet column and applying the Data Analysis tool
found {{{mu = .38}}} and {{{sigma = .1923}}} for this sampling.
{{{t = (.38 -.4)/(.1923/sqrt(5))}}} = -.02/.086 = -.2326
P(t < -.2326) = .4080 Or 40.80%
The test results would show that this sampling is well within the average
of mu = .4sec
