Answer:
76.881 minutes
Step-by-step explanation:
If we look for the value of 25% in the normal distribution table, it corresponds to z = - 0.674
I mean:
P( Z < - 0.674) = 0.25
Now, we know that the formula in this case would be
cut off time = m - z*sd
where m is the mean and sd is the standard deviation.
replacing these values we have left:
cut off time = 72.5 - (-0.674)*6.5
cut off time = 76.881
Therefore the time limit would be 76.881 minutes
