To determine whether themean nicotine content of a brand of cigarettes is greater than the advertised value of 1.4 milligrams, a health advocacy program tests:

Ho: mu = 1.4

Ha: mu > 1.4

The calculated value of the test statistic is z = 2.42.

==> How do I calculate the p-value from just this z-statistic? Thanks for your help!
