Answer:
3rd one
Step-by-step explanation:
Answer:
The minimum sample size required to construct a 95% confidence interval for the population mean is 65.
Step-by-step explanation:
We are given the following in the question:
Population standard deviation,

We need to construct a 95% confidence interval such that the estimate is within 0.75 milligrams of the population mean.
Thus, the margin of error must me 0.75
Formula for margin of error:


Putting values, we get,

Thus, the minimum sample size required to construct a 95% confidence interval for the population mean is 65.
-1. Plug in -3 for x which makes 9-10 so -1

Linear graphs:
1, 4, and 6
Non-linear graphs:
2, 3, and 5
Explanation:
Linear graphs are straight line, non-linear graphs are not straight lines.
