In a particularly small region in the Philippines, the consumer price index C depends on E, the current value of the gross regional domestic expenditure;P, the number of people living in poverty; and• F, the average number of household members in a family.In particular, C = 100 +-EPwhere e denotes Euler's number. It is known that thegross regional domestic expenditure is decreasing at the rate of PhP 50 per year; whilethe number of people living in poverty and the average number of householdmembers in a family are increasing at the rate of 3 and 1 person per year, respectively.How fast does the consumer price index change per year when E = 1000, P = 200,and F = 5?

Burkina Faso, a landlocked country in West Africa, has the lowest adult literacy rate in the world (25.3%). Over the past 15 years, the government has focused heavily on improving access to education across the country. Between 2008 and 2015, the primary school completion rate rose from 40% to 60%, and the high school completion rate doubled over the same period from 15% to 30%. Despite these encouraging statistics, children in rural areas, especially girls, continue to have limited access to quality education. You put together a survey to collect information on the following variables and you are ready to analyze: Gender Age at last birthday Distance from school Level of education (Primary, Secondary, Post-Secondary) Discuss what measure of central tendency is the most appropriate for each variable making sure to explain why.

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.A sample of 80 stocks traded on the NYSE that day showed that 11 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly less than 0.3. You use a significance level of α=0.02α=0.02.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = The p-value is... less than (or equal to) αα greater than αα This test statistic leads to a decision to... reject the null accept the null fail…
