    The value for p <0.1 i. e. 0.02088 that means, we had success in test on potassium content

    Step-by-step explanation:

    Given:

    Means: 138 mg

    sample size = 40

    New mean=136.9 mg

    To find : Hypothesis on test.

    Solution:

    We know that,

    Z = (X-mean) / standard deviation) / { (sqrt (sample size) }

    Consider the standard deviation of 3.00 mg

    Z = (136.9-138) / (3/sqrt (40))

    =-1.1/0.4743

    Z=-2.3192

    two tailed test

    =2{ (1-p (
    P value for Z=2.3192 is 0.98956

    =2{1-0.98956}

    =0.02088

    The value for p <0.1

    we had success in test on potassium content.
