Use the following data to calculate the percentage difference due to gender and comment

Question

events (world record)         1975            1985             1995               2005

men's 100m                       9.95s           9.93s            9.84s              9.77s

women's 100m                  11.07 s        10.76s           10.49s            10.49s  

men's 1500m                   3 min 32.2s   3 min 29.7s   3 min 82s       3 min 26.0 

women's 1500 m              4 min 1.4s     3 min 52.4s   3 min 50.46s  3 min 50.0 s

Answer 1

 

The formula for percent change is  (new # - old #) * 100% / old #

 

In this case, I use the men's time as the old # and the women's time as the new #

 

So it is ( men - women)*100%/men

 

So for example, in 1975, the 100 meter dash is

  (11.07 - 9.95)*100%/9.95 = 11.2562814%

 

 

The the times must be converted from minutes to seconds.

So for example, 1 minute and 10 seconds = 1*60 + 10 = 70 seconds

because there is 60 seconds in 1 minute

 

 

                       1975                    1985                        1995                       2005

men  100m       9.95                      9.93                        9.84                         9.77
women 100m   11.07 11.256%      10.76 8.359%         10.49 6.606%           10.49 7.369%

men 1500m      212.2                    209.7                      262                           206
women 155m    241.4 13.761%      232.4 10.825%        230.46 -12.038%      230 11.650%

 

 

So with the exception of 1 event, the men's times were faster by the percentage shown in bold.

The EXCEPTION is the 1995 1500 meter dash. In that event, the women's times were faster

 by slightly more than 12%, as shown with the NEGATIVE value in bold, underline, and italic font.
