Best ResponseYou've already chosen the best response.2a distribution curve has an area of 1 underneath it. since this is a uniform distribution. the "curve" is just a rectangle box with an area of 1 since the width is 7 units wide; the height of the box would have to be 1/7 to get an area of 1

Best ResponseYou've already chosen the best response.0hmm...that's an intuitive way of solving it....and here i thought i have to do \[\huge \int \limits_a^b f(x)dx\]

Best ResponseYou've already chosen the best response.2a z table is a table of probabilities; it is written up for the same reason that sin and cos tables are written up. So that we dont have to suffer thru the integration of some ungodly looking integral

Best ResponseYou've already chosen the best response.0anyway...this would just be \[\int \limits_a^b \frac 1{ba} dx\] yes?

Best ResponseYou've already chosen the best response.0\[\int \limits_a^x \frac 1{ba}dx\] yes?

Best ResponseYou've already chosen the best response.2if you wanted to do the \[\int f(x)dx\]then a uniform distribution is a constant function \[\int_{5}^{12}k~dx=1\] \[12k5k=1\] \[7k=1\] \[k=\frac17\] therefore \[\int_{6}^{9}\frac17~dx\]

Best ResponseYou've already chosen the best response.21/(ba) does generalize it yes. but the interval [a,x] seems a little off. that should simply be the interval across which you are integrating and should prolly not be confused with the other parts
