    See explanation for step by step explanations.

    Explanation:

    Let X be the mass of a randomly selected resistor

    The probability density function is given as

    , 80
    =0, otherwise

    a) By using the given pdf we have to find the probability of the resistors having resistance less than 90

    =

    =

    =0.0625

    the probability of the resistors having resistance less than 90 is 0.0625

    Step 2 of 4<

    /p>

    b) we have to find the mean resistance

    Mean=

    =

    =

    =106.67

    The mean resistance is 106.67
