A manufacturer fills jars with coffee. The weight of coffee, X
grams in a jar can be modeled with a normal distribution with a
mean of 232 grams and a standard deviation of 5 grams.

    b.      the number a
such that P open parentheses 232 less than X less than a close
parentheses equals 0.2
232 234.65 Not listed 237 229.35
    c.       the
probability it needs more than two attempts to find two jars of
coffee weight more than 224 grams is
0.9452 0.1066 0.8934 Not listed 0.0548
     d.      If we
have only five jars filled with coffee, what is the probability
exactly two of them have weight more than 232 grams.
