A cognitive psychologist is comparing ADHD children to a sample of non-ADHD controls using an established measure of reaction time that captures attention span. The mean difference is 150 (the ADHD group mean is higher by 150 points), with a confidence interval for the mean difference ranging between 25 and 350. Which of the following population parameters are not supported by the data? That is, if the following values were used as the null hypothesis, which value(s) would the data refute? CHECK ALL THAT APPLY. Select one or more:
a. 500
b. 50
c. -23
d. 0
e. None of the above

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
