Question

construct a stemplot showing life expectancies of males in eight nations. round to the nearest year and use split stems. then write a brief interpretation of the stemplot. complete the stem - and - leaf plot below. life expectancy of males (type whole numbers. use ascending order.) interpret the stem - and - leaf plot. a. the life expectancy of males appears to be unimodal and skewed left. b. the life expectancy of males appears to be bimodal and symmetric. c. the life expectancy of males appears to be unimodal and symmetric. d. the life expectancy of males appears to be unimodal and skewed right.

Explanation:

Step1: Recall mode - type concepts

Unimodal means one mode, bimodal means two modes. Symmetric data has a balanced shape around the center, skewed - left has a long left - tail and skewed - right has a long right - tail.

Step2: Analyze the stem - and - leaf plot (assume we have constructed it correctly)

Without seeing the actual constructed stem - and - leaf plot, we can't visually determine the shape precisely. But we know the definitions. If the data has one peak and the right - hand side of the distribution extends further out than the left - hand side, it is skewed right.

Answer:

We need to first construct the stem - and - leaf plot. After constructing it, if there is one mode and the tail on the right side is longer, the answer is D. The life expectancy of males appears to be unimodal and skewed right.
