The picture in the attached figure
let
x--------> men voters
y-------> women voters
we know that
y=x+2800------> y-x=2800------> equation 1
step 1
find the percentage of women and men voters
in the graph
central angle by men voters=130°
central angle by women voters=(360°-130°)-------> 230°
by using proportion
men voters
%
women voters
%
remember equation 1
y-x=2800
so
F-M=63.89%-36.11%----> 27.78%
if 27.78% correspond to 2800 voters
100%---------------------->T
T=100*2800/27.78-------> T=10,079.19 voters
the answer is
about 10,079 voters

Answer: 0.4302
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
Also, these distances are normally distributed.
Then , the formula to calculate the z-score is given by :-
For x=32.5
For x=40.5
The p-value =
Hence, the required probability :-0.4302
