Answer:
Test statistic = - 2.33
Pvalue = 0.010 (3 decimal places)
Step-by-step explanation:
Given :
H0: p = 0.25 vs Ha: p < 0.25
Phat = 0.15
Sample size, n = 102
α = 0.05
The test statistic :
(Phat - p) / (√p(1 - p) /n)
1 - p = 1 - 0.25 = 0.75
(0.15 - 0.25) / (√0.25(0.75) /102)
-0.1 / √0.0018382
-0.1 / 0.0428742
Test statistic = - 2.33
The Pvalue using the test statistic score obtained :
P(Z < - 2.33) = 0.0099031 = 0.010
Pvalue < α ; Reject H0

Answer:
The equation is 12x=180. You worked for 15 hours.

Do 12x=180 then divide by 12. You get x=180/12. Then simplify
Answer:
-2
Step-by-step explanation:
f(-6)=x^2+8x+10
f=(-6)^2+8(-6)+10
f=36-48+10
f(-6)=-2
