So far, we have only focused on estimating the mean living area in homes in ames. # now you'll try to estimate the mean home price. # .take a random sample of size 50 from price . using this sample, what is your # best point estimate of the population mean?

If samples of size 50 are taken, the distribution of the sample arithmetic mean must be approximately normal. The arithmetic mean is an unbiased, efficient, sufficient and consistent estimator of the population mean. Therefore, the best punctual estimator of the population mean is the sample arithmetic mean (the sum of the 50 values of the housing prices divided by 50).

Step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
