1) Find some scientific paper that uses standard deviation, confidence interval, correlation coefficient, or some other big idea that we talked about in our last two classes. Evaluate their use of it, and explore any differences in the ways we talked about it and how you perceive them to have used it. SEND ME A LINK TO THE PAPER YOU USE.
2) Below are three columns: human years, cat years, and dog years.
we are going to assume that human years are the explanantory and they other two are response. find hte lines of best fit for the following:
human years to dog years
what's the correlation?
human years to cat years
what's the correlation?
dog year to cat years (for this, make dog the explanantory)
what's the correlation?
if my dog has lived four years, how old would she be (according to your line of best fit)
if my cat is 95 in cat years, about how old is that in human years?
