Hi. Lovely stuff, but your conclusions to your hypothesis tests are WRONG!
You can NOT conclude that the coin is biased or unbiased, or that the new drug is or is not better than the old one.
You only have evidence to either support the claim being made, or not.
My conclusion to the coin problem:
Accept H0 (or do not reject H0). There is insufficient evidence to suggest the coin is biased.
My conclusion to the drugs question:
Accept H0. There is insufficient evidence to support the doctors claim.
QQQ Question 3: This is a test using the normal distribution, so isn't in Stats 1.
QQQ Question 4: The size of the sample isn't given (how many weeks Tessa recorded sales and temperature), so it's impossible to know what the CV should be. The mark scheme implies n=8, however.
I have a question about slide 15. It makes no sense to me, to choose 7 as the critical value, as the significance level was reached at 6. Can you explain - or is this an error?
Thank you! you made statistics bearable ;)
With the new A level course is the stats and mechanics in the one paper??? Hopefully i have got this right This current academic year students need to complete P1 and then next year They complete P2 along with their mechanics and stats
Love these fantastic resources, LEGEND
great teaching recources - thank you
Thank you very much for these free, helpful resources. I appreciate your hard work into these slides
Hi guys. I love maths :)
These resources are fantastic. I have taught Core for many years but never Stats. Thank you for your help.
Thank you dr frost
