Question

The percent of area beyond z equals 1.44 is 

Answer 1

z-scores are found in a table.  There are also calculator apps for z-scores.

 

You may "check" your table reading ability: 

  -  a z-score of 0 occurs at the mean (the 50% mark)

  -  a z-score of 1.0 is 1.0 standard deviations above the mean (84.1% to the left)

  -  a z-score of 2.0 is 2.0 standard deviations above the mean (97.7% to the left)

 

A z-score of 1.44 has 92.5% of the area (probability) to the left.  So, 7.5% is to the right (total=100%).
