28) through 33) the heights of 1000 students in a college are normally distributed with a mean 5’10” and SD 2”. Use 68% for the region from the mean to 1-SD on either side; 94% for the region from the mean to 2-SD on either side and 98% for the region from the mean to 3-SD on either side. Find the approximate number of students in each range of the heights:
\n" ); document.write( "28) 5’8”–6’
\n" ); document.write( "z(5'8\") = (5'8\"-5'10\")/2\" = -2\"/2\" = -1C
\n" ); document.write( "P(6\") = (6\"-5'10\")/2\" = 2\"/2\" = 1
\n" ); document.write( "P(5'8 to 6') = P(-1<= z <=1) = 68% = 0.68
\n" ); document.write( "--------------------------
