Jul 13, 2021 · Finding z=0.11 on the z Table, we see that p = 0.543860. This is the probability that a score will be lower than our raw score, but the question asked the proportion who would be taller. Final Answer (in words): The probability that a woman in the U.S. would be 64 inches or taller is 0.4562, or 45.62% 45.62 %. Your turn! ˉx = 28.55, ˜x = 28, mode = 28. ˉx = 2.05, ˜x = 2, mode = 1. Mean: nxmin ≤ ∑ x so dividing by n yields xmin ≤ ˉx, so the minimum value is not above average. Median: the middle measurement, or average of the two middle measurements, ˜x, is at least as large as xmin, so the minimum value is not above average.Solution: Null hypothesis—Mean number of flowers are same in two dates of recording.
