The Consumer Price Index provides a means of determining the purchasing power of the U.S. dollar from one year to the next. To use the Consumer Price Index to predict a price in a particular year, we can set up a proportion and compare it with a known price in another year as follows:(price in year A)/(index in year A)=(price in year B)/(index in year B)In 1986 the Consumer Price Index was 109.6 and in 2010 it was 218.1. Find the amount that would be charged in 2010 for the use of the same amount of electricity that cost $110 in 1986. Give your answer to the nearest dollar.

Real wage is a wage deflated by the current consumer price index. It gives information on how much current wage compares to the wage of given base year period. Real wage is obtained by dividing the nominal wage by the current Consumer Price Index (CPI) of a given month multiplied by 100. Table 1 below presents the real wage and nominal wage of non-agriculture workers in the Philippines as of December 2019 by region. Referring to the data, how many regions are below the 4th decile of the real wage?A. 4B. 5C. 6D. 7Referring to the data, how many regions are above the 80th percentile of the nominal wage?A. 4B. 5C. 6D. 7

The analysis of the results of a budget survey of 150 families gave an average monthly expenditure of Rs. 120 on food items with a S.D. of Rs. 15. After the analysis was completed it was noticed that the figure recorded for one household was wrongly taken as Rs. 15 instead of Rs. 105. Determine the correct value of the average expenditure and its S.D.

A study was carried out to determine the influence of a trace elementfound in soil on the yield of potato plants grown in that soil, defined asthe weight of potatoes produced at the end of the season. A large fieldwas divided up into 14 smaller sections for this experiment. For eachsection, the experimenter recorded the amount of the trace elementfound (in milligrams per metre squared) and the corresponding weightof the potatoes produced (in kilograms). This information is presentedin the worksheet ‘Dataset5’ in the Excel document. Define X as thetrace element amount and Y as the yield.1. Draw a scatterplot of your data set.Page 52. Calculate the coefficients of a linear equation to predict the yieldY as a function of X.3. Calculate the correlation coefficient for the paired data values.4. Set up the framework for an appropriate statistical test to establish if there is a correlation between the amount of the trace element and the yield. Explain how having the scatterplot referredto…
Body mass index (BMI) is a measure of body composition, which can be used to assess if someone is underweight, healthy weight, overweight but not obese, or obese. It is calculated as a person’s weight (measured in Kilograms) divided by his/her height (measured in meters) squared. We recorded 5 students’ BMI values and the numbers of hours they exercised in the past week, as following: BMI 18.4 19.6 20.5 27.6 30.6 Hours of exercise 3.0 2.5 4.0 2.7 0.5 What is the value of r?
