Answer:
The probability that the sample proportion of 80 LL70 batteries is within 0.03 of the population proportion is 0.44
Step-by-step explanation:
Sample proportion being within margin, or margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the corresponding statistic of the probability that the sample proportion is within the 0.03 of the population proportion
- p is the claimed proportion (86% or 0.86)
- N is the sample size (80)
Then 0.03=
from this we get:
z≈0.773 and the p(z)≈0.439
Therefore, the probability that the sample proportion is within 0.03 of the population proportion is 0.44
The answer is C.
-k just means the opposite of the k values

Answer:
3.9581139448
Step-by-step explanation:
8 ÷ 3 + 13
8 ÷ 3 = 2.66666667
2.66666667 + 13 = 15.6666666
square root of 15.6666666 is 3.9581139448
