A defense company working for the government claims that at most 6% of its missiles are defective. A sample of 160 missiles is t
aken and 16 are defective. Test their claim at 1% level.
Required:
State clearly the null and the alternative hypothesis
1 answer:
Answer:
Null Hypothesis: H0: Defective defense missiles not more than 6%
Alternate hypothesis: Ha: Defective defense missiles are greater than 6%
Step-by-step explanation:
The null hypothesis is the problem statement and the alternate hypothesis is a contradiction of null hypothesis
Hence,
Null Hypothesis: H0: Defective defense missiles not more than 6%
Alternate hypothesis: Ha: Defective defense missiles are greater than 6%

given W = XYZ
to isolate Z divide both sides by XY
= Z ⇒ Z = ![\frac{W}{XY}](https://tex.z-dn.net/?f=%5Cfrac%7BW%7D%7BXY%7D)

Value of x is 1/5
Step-by-step explanation:
- Step 1: Given equation is 4 = √6x + 15 - x. Square both sides of the equation.
⇒ 16 = 6x + 15 - x
⇒ 16 = 5x + 15
⇒ 1 = 5x
∴ x = 1/5
X = 12
Use the Pythagorean Theorem.
13^2 = 5^2 + x^2
169 = 25 + x^2
Subtract 25 from both sides.
144 = x^2
Take the square root.
12 = x
