If you assume the normal model for these data, in about what percent of countries would the percentage of people 65 and older be more than 0.22? In about what percentage of countries would the percentage of people 65 and older be less than 0.14? ### Item 1: Percentage of Population Aged 65 and Older#### Graph DescriptionThe graph shown is a histogram representing the distribution of the percentage of the population aged 65 and older across various counties. The x-axis denotes the "Percentage of seniors (aged 65 years and over) in each county," with values ranging from 1% to 55%. The y-axis represents the "Number of counties."#### Analysis1. **Central Tendency:** - The peak of the histogram is observed between 15% and 19%, indicating that the most common percentage of seniors in many counties falls in this range. 2. **Dispersion:** - The distribution shows a bell-shaped curve, suggesting a normal distribution of the percentage of elderly population across counties. - There are relatively fewer counties where the senior population is either below 5% or above 30%, indicating that extreme values are less common.3. **Data Points:** - The highest number of counties, approximately 300, have around 18% of their population aged 65 and older. - As the percentage of elderly population increases beyond 20%, the number of counties decreases steadily.4. **Skewness:** - The graph is slightly right-skewed as there are a few counties with higher percentages (above 20%) of elderly population.#### Educational InsightsUnderstanding the distribution of the elderly population can aid in:- Resource allocation: Planning for healthcare, senior housing, and social services.- Policy making: Creating targeted policies for aging populations.- Demographic studies: Examining aging trends and preparing for future demographic shifts.This histogram effectively highlights the need for a balanced approach in elderly care and services across various counties, reflecting the demographic realities of aging populations.

The table below shows the number of state-registered automatic weapons and the murder rate for several states in the U.S. 11.6 8.4 6.7 3.5 2.7 2.7 2.2 0.9 14.1 11.3 9.9 6.8 6.2 6.3 5.8 I = thousands of automatic weapons y = murders per 100,000 residents Keep in mind, the data in the table do not necessarily imply a direct causal link between the two variables. (In fact, can you think of any reasons why these variables may not be directly related to each other?) Also, the purpose of this question is not to make a political statement about guns or gun control. It's only to illustrate that data such as these sometimes have mathematical relationships that can be modeled with linear equations. Those relationships should always be questioned and examined carefully. With that said, these data can be modeled by the equation y = 0.87z + 3.95. Use this equation to answer the following; A) If this model is oconsistent, how many murders per 100,000 residents can be expected in a state with 8.7…
A linear model was fit to predict weekly Sales of frozen pizza (in pounds) from the average Price ($/unit) charged by a sample of stores in a city in 39 weeks over a three -year period. The average Sales were 63, 200 pounds (SD = 10, 670 pounds), and the correlation between Price and Sales was -0.529. If the Price in a particular week was two SD higher than the mean Price, how much pizza would you predict was sold that week?

The data used is from college campuses. The variables used in the analysis below include: crime, total campus crime; enroll, total enrollment; police, employed officers. Use the estimated OLS models to answer the questions below: Model A: In(crime) = -6.631 + 1.270ln(enroll), (1.034) (.110) .5804 n = 97; R² = Model B: In(crime) = -4.794+.923ln(enroll) +.516ln(police), (.144) (.149) (1.112) n = 97; R² = .632 Using Model A, test the null hypothesis that elasticity of crime with respect to enrollment is unit elastic, i.e. equal to one (against a two-sided alternative).
