The null hypothesis H0 would be rejected if your test statistic 'z' is greater than your hypothesized mean.  In this case, it is 4.8 lbs/square inch.  Keep in mind that your value in this problem must be rounded to 2 decimal places.  And since 4.8 has one decimal place, we would include an extra trailing 0 at the end.  Meaning that 4.8 becomes 4.80


SOLUTION:       Reject H0 if  z > 4.80   (In other words, 4.80 would go into your answer box)
