  1. It is discovered that there is a 0.3934, or 39.34%. likelihood that a customer waits fewer than 30 seconds using the exponential distribution.

    Define the term exponential distribution?

    • The exponential distribution is a mathematical distribution used in test statistic that frequently addresses the amount of time until a given event occurs.
    • Events occur continually, independently, and at a steady average pace during this process.
    The following equation describes an exponential probability distribution with mean m:
    f(x) = μe∧(- μe)
    The decay parameter is in the following:
    μ = 1/m
    When x is less than or equal to a, the probability is given by:
    P(X ≤ x) = ∫ f(x) dx (limits 0 → a)\
    which can be resolved as follows:
    P(X ≤ x) = 1 – e∧(- μe)
    Since 60 seconds is the mean in this problem, then decay parameter is:
    μ = 1/60
    The likelihood that a customer will wait under 39 seconds is:
    P(X ≤ 30) = 1 – e∧(- 30/60)
    P(X ≤ 30) = 0.3934
    Thus, the probability that a consumer will wait less than 30 seconds is 0.3934, or 39.34%.
