Answer:
Option c.
Step-by-step explanation:
Confidence interval refers to an interval such that there is a probability that the value of a parameter lies within that interval.
Therefore,
the confidence interval of the mean means that there is a probability that the value of a parameter lies within that confidence interval.
So, option c. is correct
X = number of $85 trees, y = number of $95 trees
Logically, we can construct the expression 85x + 95y to represent how much Maple Grove spends on their trees in total. They want this cost to be less than or equal to $95,000. This means that the inequality has to be 85x + 95y ≤ 95000, either choice a or b. Since the community wants more $95 trees, they want y to be greater than or equal to x.
This means choice b: 85x + 95y ≤ 95000<span>, x</span>≤y is your answer.
Hope this helps!
Answer:
Step-by-step explanation:
Answer:
The region between one standard deviation from the mean is (400,600) which should be 68.27% of the data.
Step-by-step explanation:
The mean of this data set is 500 and the standard deviation is 100. The data that are within one standard deviation of the mean, must be in the range between 400 and 600, which according to the normal curve should be about 68.27% of the samples. The shaded region is shown in red on the attached figure.
