Answer:
The correct option is option c.
H0: p not equal to 0.5
H1: p equal to 0.5
Step-by-step explanation:
1. H0: p not equal to 0.5
H1: p equal to 0.5
2. P cap = 104/ 260
P cap = 0.4. ( where p cap is the sample proportion)
3. Find the test statistic
Using : Z = ( p cap - p) /√ [(p ×q)/n] where p = 0.5 q= 1-p = 0.5. n=260
Z = -3.23
4. P value = 0.006
5. Since p value is less than the alpha level (0.01) . we reject the null hypothesis and conclude that the touch therapists are not effective.

9) Area of Figure = Area of rectangle + area of triangle
A = 17 * 22 + (1/2 * 12 * 19)
A = 374 + 114
A = 488 cm²
10) Area of Figure = Area of rectangle + area of triangle
A = 8 * 4 + (1/2 * 3*4)
A = 32 + 6
A = 38 cm²
Hope this helps!
Hey there! Your answer us -24° And here you would use subtraction. Hope this helped!! Your fellow Brainly user, GalaxyGamingKitty.
Answer:
Step-by-step explanation:
(a²-b²) / (a+b) = 12
a² - b² = 12(a+b)
(a-b)² + 2ab - 2b² = 12a + 12b
(a-b)² = 12a + 12b - 2ab + 2b²
a - b =
