Okay don;t know how to explain how to solve this but the answer is, 43.35 that is the answer.
Answer:
(a) The z-critical value for a left-tailed test, for a significance level of α=0.05 is -1.64.
(b) Since -1.54 > -1.64, therefore we accept H₀.
Step-by-step explanation:
(a)
It is given that the value of test statistic is
![z=-1.54](https://tex.z-dn.net/?f=z%3D-1.54)
We need to test the claim that p<0.18.
Null hypothesis: ![H_0:p=0.18](https://tex.z-dn.net/?f=H_0%3Ap%3D0.18)
Alternative hypothesis: ![H_1:p](https://tex.z-dn.net/?f=H_1%3Ap%3C0.18)
It is a left tailed test.
Significance level:
![\alpha=0.05](https://tex.z-dn.net/?f=%5Calpha%3D0.05)
The z-critical value for a left-tailed test, for a significance level of α=0.05 is -1.64.
(b)
It is a left tailed test and critical value is -1.64 it means the region on left of -1.64 is rejection region.
The value of z is -1.54 and the critical value is -1.64.
We know that -1.54 > -1.64.
Therefore we accept H₀.
Answer:
x= ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)

Answer:
The answer is 3,019.92 cubic millimeter
Step-by-step explanation:
take 375 plus 375 to get 750
then 3769.91 - 750 to get the 3,019.92
Answer: X = 17
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x−5)=24
(2)(x)+(2)(−5)=24(Distribute)
2x+−10=24
2x−10=24
Step 2: Add 10 to both sides.
2x−10+10=24+10
2x=34
Step 3: Divide both sides by 2.
2x
/2 = 34/
2
x=17
