Que The accompanying data on annual maximum wind speed (in meters per second) in a city for each year in a 45-year period were given

30.2, 38.9, 34.0, 38.5, 44.7, 31.5, 26.6, 51.8, 31.8, 27.3, 53.0, 45.7, 63.4, 36.1, 63.9,31.3, 42.3, 41.0, 37.1, 34.5, 35.6, 62.3, 30.4, 40.1, 35.9, 39.5, 34.3, 28.2, 39.0, 55.1,35.1, 28.7, 25.6, 62.6, 32.3, 32.0, 37.4, 31.4, 32.1, 35.4, 37.4, 41.1, 37.4, 48.7, 28.2

 Part (a) Use the annual maximum wind speed data to construct a histogram.

Part (b) Is the histogram approximately symmetric, positive skewed, or negatively skewed?

(A) The distribution of maximum wind speeds is positively skewed.

(B) The distribution of maximum wind speeds is negatively skewed.

(C) The distribution of maximum wind speeds is approximately symmetric.

 

Part (c) Would you describe the histogram as unimodal, bimodal, or multimodal?

(A) The distribution is multimodal, with at peaks at the 25-30, 45-50 and 60-65.

(B) The distribution is bimodal, with peaks at the 35-40 and 60-65 intervals.

(C) The distribution is unimodal, with a peak at the 35-40.

(D) The distribution of bimodal, with peaks at the 40-45 and 50-60 intervals.
