Action:
Use the above data and multiple regression to produce a model to predict Morning Starthe average price of gold from other variables. Comment on the following:
- Regression equation & describing equation
- R, R2 and 1-R2, adjusted R2 & interrupting each one
- Standard error of estimate & interpretation
- Report the t's for each value and the corresponding p-values
- Overall test of hypothesis and decision.
- Use a .05 level of significance. Cite which variables are significant and which are not significant, based on the t values and p values for each independent variable.

Highland Mining and Minerals Co. is considering the purchase of
two gold mines. Only one investment will be made. The Australian
gold mine will cost $1,671,000 and will produce $381,000 per year
in years 5 through 15 and $592,000 per year in years 16 through 25.
The U.S. gold mine will cost $2,041,000 and will produce $267,000
per year for the next 25 years. The cost of capital is 8 percent.

The U.S. Census Bureau announced that the median sales
price of new house sold in December of 2018 $322,800, and the mean
sales price was $376,000
(https://www.census.gov/construction
/nrs/pdf/uspricemon.pdf). Assume that the standard
deviation of the prices is $90,000.
a. If you select a random sample of n = 100, what is the
probability that the sample mean will be less than
$300,000?
b. If you select a random sample of n = 100, what is the
probability that the sample...

1. Based on U.S. Bureau of Justice data, 16% of persons arrested
are women. If 400 arrest cases are randomly selected, estimate the
probability that more than 60 women were arrested. Since this is
discrete data, use the binomial distribution.
I got the answer 0.628 and it is not correct.
2. The lengths of human pregnancies are normally distributed
with a mean of 268 days and a standard deviation of 15 days. If we
stipulate that a baby is premature...
