Answer:
So the value of the test statistic is -0.85.
Step-by-step explanation:
We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.

We calculate the standar deviation:
We calculate the value of the test statistic:
So the value of the test statistic is -0.85.
Answer:
375 pound is needed for 3/4 as we can show 125 pound each 1/4 acre
Step-by-step explanation:
3/4 of an acre = 3/4 of 500 = 375
1/4 = 125
125 x 3 = 375
K=7r-s
Add s to both sides
k+s=7r
Divide both sides by 7
Final Answer: k/7+s/7=r
The first option 0.65 might be right
