Answer:
Average rate of change for the number of African American women who held office at any given time between 1970 & 1993 is 94.43.
Step-by-step explanation:
Here, according to the question:
Number of African American women in elected public office in the United States in the year 1970 = 160
Number of African American women in elected public office in the United States in the year 1993 = 2332
Now, the change in the number of elected women between 1970 & 1993
= Women elected in the year 1993 - Women elected in the year 1970
= 2332 - 160 = 2,172
or, the change in the number of elected women candidates between 1970 & 1993 is 2,172
