Complete parts (a) through (e) below. ... B. In 100 randomly sampled surveys of 20 adults, exactly 10 out of the 20 adults would be expected to be satisfied with the airlines in about 9 of those surveys. C. In 100 randomly sampled surveys of 20 adults, 10 or more of the 20 adults would be expected to be satisfied with the airlines in about of those surveys.
