A study was conducted to determine the proportion of people who dream in black and white instead of color. Among people over the age of 55, dream in black and white, and among people under the age of 25, dream in black and white. Use a significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
