To figure out the answer for this question I used the normalcdf function on my calculator.. it looked like this when i punched it in...
normalcdf(195,E99,176,7)
The answer that I got was .0033 or .33% chance of males that will not get the job because they are too tall.

i did normalcdf(168,195,176,7) and i got 87.01%... i think this is the percentage that DOES qualify though.... i tried to do it a different way and i got like...umm .0033 which doesn't seem right... unless its 33%... anyone know what i did wrong?

for this question I used ron blond's site for part a.) I found that the percent of males too tall for the agency is roughly 87%. I'm not sure how to do part b.) but I'm working on it..

This one confused me. I thought if you use normalcdf and calculate who qualifies for Males you would get .87 and females you would get .73.
If you subtract 100 from these totals, i assumed the the .13 and .27 represent all those who dont qualify, however I didn't take into account that some could be shorter. I havent arrived at an answer yet but thanks Ben, that makes sense.

On this question I only could get the first part and for that I got .0033 because I put Normalcdf(195,E99,176,7)..You put the E99 becuase you want the males who will not qualify. Like I said I didn't know how to do the other parts..it quite confused me

To figure out how to figure how many males will be to tall, I just drew a bell chart and just figured it out in my head. And I got an answer of .7% of males will be to tall. To figure out who has a better chance of getting hired I used the normal cdf method, and i got that males have an 87% chanse of getting hired while the females only have a 73% chance. TO figure out the new minimum height of the females will be 156 cm, I just used tral and error.

I didn't know how to do this question...but Ben's way makes sense and the answer seems reasonable..

I used the cdf method for a.) and got 14%
And for B.) I used the Z= method and got -.33. and i didnt get C.)

I used the website to find this answer, I got 81% for the first part of this question, then I used normalcdf and then got maybe a better percentage of 33%, not sure if I got it right...sorry about the phone

This is Dustin, for 12 a) I got an answer of 15% not being able to qualify because they are too tall and for 12 b) I got that they don't have an equal cahnce of being hired between the males and the females

for part b.) I used normalcdf and came up with 73%, from what Mr. Max just said I think that this is the percent that don't get hired so, 27% of females get hired. likewise, 13% of males have a chance of getting hired(because my calculator said 87%) ...or is it the other way around? I don't know. I'm more than a little lost.
