In a sample of 62 cups, the average diameter was found to be 3.07in. with a standard deviation of 0.21. give a point estimate for the population standard deviation of the diameter of the cups. round your answer to two decimal places, if necessary.

Population standard deviation (σ) = 0.3 in

Step-by-step explanation:

Sample mean = 3.07 in

Sample standard deviation (s) = 0.21 in

Sample size (n) = 62 cups

Population standard deviation (σ) = ?

The point estimate for the population standard deviation is given by sample standard deviation divided by the square root of the sample size:

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
