like how would i solve it without using Excel or something like that

You would use a ztable or calculator Do you use a table ?

Here is a site that does the conversion http://www.tutorhomework.com/statistics_tables/statistics_tables.html How are you doing these problems?

this is the first one like this on my hw

your book must talk about how to do this?

phiBest ResponseYou've already chosen the best response.1
but to do a) select standard distribution (the first one shown) right tail type in 0.966 for z and have it calculate the area under the curve to the right of that z score. that is the chance the weight is above this z score

any way this can be done on a graphing calc rather than on this site?

if it knows about normal distributions (do they?) otherwise http://en.wikipedia.org/wiki/Normal_distribution#Numerical_approximations_for_the_normal_CDF is a (messy) way

REMAINDERBest ResponseYou've already chosen the best response.0
using normal since ur z score is 0.966 round to 2 decimal u'll have 0.97 it means u'll have P(z>=0.97) because it is over 1050 u'll have 1P(Z<=0.97) on the z table 0.97 it hase the probability of 0.1660 now 1(0.1660) 0.834 wich by conclusion is 83.4%

mariomintchevBest ResponseYou've already chosen the best response.0
yeah i get everything except the part where i get the 0.1660. i dont know how to get it without using the site Phi gave me above. ^^^

mariomintchevBest ResponseYou've already chosen the best response.0
yes i get that by doing the formula for z score and rounding

do u see the value that correspond to it ?

not really no. i dont get how that part works.

dw:1348601547745:dw the deshes represents some numbers on the table ;right
 one year ago

mariomintchevBest ResponseYou've already chosen the best response.0
yeah. i just dont know how i get this table to see the probability.
 one year ago

REMAINDERBest ResponseYou've already chosen the best response.0
to find this 0.1660 take 0.9 ignore negative (meaning u gonna take 0.9)then add it to 0.07 wich will give positive 0.97 from there where 0.9 intersects 0.07 is ypur probability
 one year ago

mariomintchevBest ResponseYou've already chosen the best response.0
yes i get that. i dont know how to get that table though.

what do you mean you dont know how to get the table?
