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.
Answer:
I need numbers to actually calculate the problem.
Step-by-step explanation:
Answer:
Natalie got 3, Veronica got 9.
Step-by-step explanation:
N = Natalie
If Veronica got 3 times as many as Natalie, then she got 3N.
Add them together:
N + 3N = 12
4N = 12
N = 3
Therefore,
Natalie got 3 (N = 3)
Veronica got 9 (3N = 3 x 3 = 9)
