To find: The percentage of fall in males is faster or rise in females is faster or vice-versa.
The percentage of females is increasing faster than the percentage of males is decreasing.
Given:
The data of labor force in the form of table is
Year | Female | Male |
1960 | 37.7 | 83.4 |
1965 | 39.3 | 80.5 |
1970 | 43.3 | 79.6 |
1975 | 46.3 | 77.2 |
1980 | 51.5 | 77 |
1985 | 54.5 | 76.1 |
1990 | 57.5 | 76.3 |
1995 | 58.9 | 74.6 |
2000 | 59.9 | 74.7 |
2005 | 59.3 | 73.2 |
2010 | 58.6 | 70.7 |
Calculation:
Calculation of slope for percentage of males.
Taking
Substitute the values in the formula
Calculation of slope for percentage of females.
Taking
Substitute the values in the formula
The negative slope of male indicates that the percentage of male is falling while the positive slope of female indicates that the percentage of female is rising.
Conclusion:
The value of slope is more in case of females than males. So, the percentage of females are increasing faster than the percentage of males are decreasing.
