    Write your answer as a percentage with 2 decimals


    = 3.59%


    Step-by-step explanation:


    The z score formula is given as:


    z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.


    Mean = 26 minutes


    Standard deviation = 1.2 minutes.
