You can put this solution on YOUR website!
Unfortunately I do not have a Z table, not to mention different Z tables calculate things differently. with me and it has been ages since I took statistics, but this should be the correct way to solve this problem.\r
\n" ); document.write( "\n" ); document.write( "You have the formula:\r
\n" ); document.write( "\n" ); document.write( "\"%28X+-+M%29%2FS+=+Z\" Where X is the data, M is the mean, and S is the standard deviation. Z is the Z score it corresponds with.\r
\n" ); document.write( "\n" ); document.write( "a) our data is 300 and 310 and we want it in between. Well, we know 310 is the mean so that is when z = 0. We do not need to check this, we need to check 300.\r
\n" ); document.write( "\n" ); document.write( "\"%28300+-+310%29+%2F+5+=+-2\"\r
\n" ); document.write( "\n" ); document.write( "Depending on your Z table, Z = -2 should correspond with some decimal. That is your answer.\r
\n" ); document.write( "\n" ); document.write( "b) with this one, you want to calculate z > 304. Once again, depending how your Z table looks at it, you will either have to do 1 - P(x=304) or .5 + p(x = 304)\r
\n" ); document.write( "\n" ); document.write( "We can begin calculating Z:\r
\n" ); document.write( "\n" ); document.write( "\"z+=+%28304+-+310%29%2F5+=+1.2\"\r
\n" ); document.write( "\n" ); document.write( "I can't really tell you how your Z table calculates probability because I have had two different Z tables in a couple different classes a few years ago.
\n" ); document.write( "
