easy statistics

[tough saffron]

ok so you find the z score and do (100000-125000)/23000 and you get -1.086

i assume you dont round it

how do you use the normal table

do you look for -1.9 wait so then would you round it

easy statistics

so you get 0.1379 from the normal probabilties table i guess and then what

is that the percentage 13 percent of homes are valued over 100000

or is it 1-0.1379 which is like 0.8621
