Answer:
a) (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
Step-by-step explanation:
Given that:
For male students: number of male students () = 69, number who liked the new method (x) = 38
For female students: number of female students () = 73, number who liked the new method (x) = 20
a) The probability that a male student like the new method () is given as:
The probability that a female student like the new method () is given as:
c = 95%, α = 1 -c = 0.05
the difference between the proportions of male and female students who like the new method better = ± = ± = (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
5x - 2 = 8x + 5.
-2 = -5x + 8x + 5
-2 = 3x +5
-7 = 3x
-7/3 = -2.3
Decagon = 10 sides or 10 anglesTotal angle is equal to 360°
360° ÷ 10 = 36°
I haven't seen the image of A, that is why, I started with angle A as 36°
∠A = 36°∠B = 36° + 36° = 72°∠C = 72° + 36° = 108∠D = 108° + 36° = 144°∠E = 144° + 36° = 180°∠F = 180° + 36° = 216°∠G = 216° + 36° = 252°∠H = 252° + 36° = 288°∠I = 288° + 36° = 324°∠J = 324° + 36° = 360°
