When designing a new thrill ride for an amusement park, the designer must consider the sitting heights of males. Listed below are the sitting heights (in millimeters) obtained from a simple random sample of adult males.
936 928 924 880 934 923 878 930 936
Answer the following Questions regarding the above data-
- Are the sitting heights from a population that is discrete or continuous?
- What is the level of measurement of the sitting heights? (nominal, ordinal, interval, ratio)
- Use the sitting heights listed above to construct a frequency distribution taking class width of 10mm and 870mm as the lower class limit of the first class.
- Does the distribution appear to be uniform, normal (bell-shaped) or skewed? (based on the result of histogram)
