Osteoporosis is a degenerative disease that primarily affects women over the age of 60. A research analyst wants to forecast sales of StrongBones, a prescription drug for treating this debilitating disease. She uses the model Sales = β0 + β1Population + β2Income + ε, where Sales refers to the sales of StrongBones (in $1,000,000s), Population is the number of women over the age of 60 (in millions), and Income is the average income of women over the age of 60 (in $1,000s).

Smoke Detector Use and Death Rates : application problem on measures of association between two variables. Smoke Detector Use and Death Rates. Over the past 40 years, the percentage of homes in the United States with smoke detectors has risen steadily and has plateaued at about 96% as of 2015 (National Fire Protection Association website). With this increase in the use of home smoke detectors, what has happened to the death rate from home fires? The file SmokeDetectors contains 17 years of data on the estimated percentage of homes with smoke detectors and the estimated home fire deaths per million of population. Compute and report the correlation coefficient. Is there a positive or negative correlation between smoke detector use and deaths from home fires? Comment. Show a scatter plot of the death rate per million of population and the percentage of homes with smoke detectors.

In Africa in 2011, the number of deaths of a female from cardiovascular disease for different age groups are in the table ("Global health observatory," 2013). In addition, the proportion of deaths of females from all causes for the same age groups are also in the table. Do the data show that the death from cardiovascular disease are in the same proportion as all deaths for the different age groups? Test at the 5% level.

A company wants to plan production for the ensuing year so as to minimize thecombined cost of production and inventory storage. In each quarter of the year, demand isanticipated to be 65, 80, 135 and 75 respectively. The product can be manufactured duringregular time at a cost of Php 16 per unit produced, or during overtime at a cost of Php 20 perunit. The given table below shows data pertinent to production capacities. The cost of carryingone unit in inventory per quarter is Php 2. The inventory level at the beginning of the firstquarter is zero.
TRUE or False 1)Logistic regression cannot be employed when the dependent variable is binary. 2)In the average linkage clustering, the distance between two clusters is defined as the average of distances between all pairs of objects, where each pair is made up of one object from each group. 3)As Monte Carlo simulation is essentially statistical sampling, the larger the number of trials used, the more precise is the result. 4)Monte Carlo simulation is an inappropriate tool to analyze cash budgets because of the inherent uncertainty of the sales forecasts on which most cash budgets are based 5)Any solution that satisfies all constraints of a problem is called a feasible solution..
