I think it’s A and B because on the top where is is 24 is M and the bottom is 25 which is L
Answer:
Decision rule for rejecting is
reject H0 is test statistic <-1.233
Step-by-step explanation:
Given that a sample of 1300 computer chips revealed that 27% of the chips do not fail in the first 1000 hours of their use, as against company literature of 29%
To test this we create hypotheses as
![H_0: p = 29%\\H_a: p](https://tex.z-dn.net/?f=H_0%3A%20p%20%3D%2029%25%5C%5CH_a%3A%20p%20%3C27%25)
(left tailed test at 10% significance level)
p difference = -0.02
STd error of p = ![\sqrt{0.29*0.71/1300} \\=0.0126](https://tex.z-dn.net/?f=%5Csqrt%7B0.29%2A0.71%2F1300%7D%20%5C%5C%3D0.0126)
Test statistic = p diff/std error = -0.1587
For 10% significance level for right tailed test we can reject H0 if
test statistic <-1.645
Decision rule for rejecting is
reject H0 is test statistic <-1.233
Answer:
I think your answer is B. -4
Step-by-step explanation:
-3*4+8
-12+8
-4
50% because the first two children have no effect on the third one
