Answer:
There is enough evidence to support the claim that the true proportion of monitors with dead pixels is greater than 5%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 300
p = 5% = 0.05
Alpha, α = 0.05
Number of dead pixels , x = 24
First, we design the null and the alternate hypothesis
This is a one-tailed(right) test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from excel.
P-value = 0.00856
Since the p-value is smaller than the significance level, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Conclusion:
Thus, there is enough evidence to support the claim that the true proportion of monitors with dead pixels is greater than 5%.
Answer:
28
Step-by-step explanation:
4x + 9x + 8x = 147
21x = 147
x = 147/21
x = 7
========
The shortest side will be 4x
4*7 = 28

<u><em>Answer:</em></u>
<u><em>X>1</em></u>
<u><em>*The answer must have a positive sign and greater than symbol.*</em></u>
Step-by-step explanation:
First, you subtract by 3 from both sides of an equation.
Then, you subtract by the numbers from left to right.
You can also divide by 2 from both sides of an equation.
Finally, you divide by the numbers from left to right.
<em><u>Final answer is x>1</u></em>
I hope this helps you!
Have a nice day! :)

Thank you so much! :)

X = 28
1/4+17=x-4
Multiply both sides of the equation by 4
X+68=4z-16
Move variable to the left hand side and change its sign
X-4x+68=-16
X-4x=-16-68
Combine like terms
-3x=-16-68
-3x=-84
Divide both sides by -3
X=28
