I'm sure some one asked the same question yesterday
yes me lol
i thought i was doing it right but it says my answers are wrong.
So you have a way of checking your answer?
yah its a math lab. u put the answer in and it says if you're right or wrong.
Ok the last time i've done statistics is 5 years ago, so I will try and work out the answer, you tell me if it's right, then i will explain the method
try 0.5 and 2.4
it says it's wrong.
To be honest to work out the confidence interval, the sample size must be >30, in this case you only have 9 specimens.
i'll find the example so maybe you can look at that. It's confusing to me.
I have to go at the moment, but I will be back in 3 hours if you haven't sorted this out by then i will help you
ok Thanks for the help. :)
Well the reason my answers were incorrect is because i didn't round up the mean or the s.d. because that would affect the results. I used the same method as you presented.
