So we're given this table here, which is the number of cents of 100 randomly selected checks.
00:07
And so the way we read this table is there were cents, there were 0 to 24 cents, and on the 100 checks, 33 of them had this sense portion.
00:18
And that's how we read this table.
00:19
And what we're doing is calculating the chi -squared test statistic for goodness of fit test.
00:24
Now, we're not told the expected fit.
00:27
We're going to go ahead and assume, because we're not told exactly, we're expecting or we believe that they're uniformly distributed.
00:40
Meaning, we observe this, the expected would be out of 100, right, because we had a total of 100 randomly selected checks, we'd expect 25.
00:50
So we'd expect 25 in each...
