Best ResponseYou've already chosen the best response.0The first thing you should do is fill in the numbers at the bottom of the graph. µ = mean σ = standard deviation Put the mean in the middle, and add the standard deviation to the right Subtract the standard deviation to the left dw:1442110705851:dw

Best ResponseYou've already chosen the best response.0So for A you want to add up the percentages between 160 and 190dw:1442110884768:dw

Best ResponseYou've already chosen the best response.0You are correct(: so I would basically do the same for part b right? fill in using the mean for b

Best ResponseYou've already chosen the best response.0well the mean and standard deviation are the same for A and B. For b they're just looking for a different range, so this time only add the percentages between 170 and 180

Best ResponseYou've already chosen the best response.0If you notice, 170 is on there too, to the left of 175. So add 34 for 170 to 175 and another 34 for 175 to 180
