Answer:
Alan = reject H0
Bill = cannot say
Step-by-step explanation:
Given that Heather is a student in a class that has been asked to conduct a hypothesis test for a population proportion.
![H0: p = 0.5 \\Ha: p ≠ 0.5](https://tex.z-dn.net/?f=H0%3A%20p%20%3D%200.5%20%5C%5CHa%3A%20p%20%E2%89%A0%200.5)
(two tailed test at 5% significance level)
Since she rejects null hypothesis p value should have been less than 0.05
when p value <0.05, it is definitely less than 0.10
So at 1% level of significance also the null hypothesis would be rejected.
So Alan also would get the same result as to reject the H0
But about Bill since Bill uses 0.01, we cannot definitely say that p value is less than or greater than 0.01
All we know is that p is less than 0.05
Hence it is impossible to tell from the information for Bill
C+3c is 4c and -4+9 is 5 so your answer is 4c+5
If the total cost was 21.35, and the poster cost 8.95, then all you need to do is subtract to poster cost from the total cost to find the cost of the pencil.
21.35-8.95= $12.40
Answer:
The student made an error during the distributive property in the second step where they multiplied 0.15 by -0.2 to equal -0.3 when it should have been -0.03.
Step-by-step explanation:
![0.15(y-0.2)=2-0.5(1-y)\\0.15y-0.03=2-0.5+0.5y\\0.15y-0.03=1.5+0.5y\\100(0.15y-0.03)=100(1.5+0.5y)\\15y-3=150+50y\\15y-3-15y-150=150+50y-15y-150\\-153=35y\\-\frac{153}{35}=y](https://tex.z-dn.net/?f=0.15%28y-0.2%29%3D2-0.5%281-y%29%5C%5C0.15y-0.03%3D2-0.5%2B0.5y%5C%5C0.15y-0.03%3D1.5%2B0.5y%5C%5C100%280.15y-0.03%29%3D100%281.5%2B0.5y%29%5C%5C15y-3%3D150%2B50y%5C%5C15y-3-15y-150%3D150%2B50y-15y-150%5C%5C-153%3D35y%5C%5C-%5Cfrac%7B153%7D%7B35%7D%3Dy)
