Concept explainers
(a)
To construct: a histogram of these 50 observations and explain about the shape.
(a)
Explanation of Solution
Given:
Calculation:
Table on the basis of given data of interval and frequency
Interval | Frequency |
0.425-0.45 | 5 |
0.45-0.475 | 8 |
0.475-0.5 | 17 |
0.5-0.525 | 6 |
0.525-0.55 | 13 |
0.55-0.575 | 1 |
Graph:
Bar graph
By seeing that the width of the bars have to be the same and the bars have to be bounded horizontally by the interval limits. The height of the bars has to be equal the frequency.
(b)
To construct: a graph of the density curve for the population distribution and the value of the population mean.
(b)
Explanation of Solution
The histogram looking roughly Normal, because the one of highest bar is in the middle of the histogram and the histogram does not displaying any strong skewed
Graph:
Bar graph
When we randomly select a number between 0and 1, then we have a uniform distribution on (0, 1).
The mean of the uniform distribution
