Asian economies impact some of the world's largest populations. The growth of an economy has a big influence on the everyday lives of ordinary people. Are Asian economies changing? A random sample of 15 Asian economies gave the following information about annual percentage growth rate.

What is the age distribution of promotion-sensitive shoppers? A supermarket super shopper is defined as a shopper for whom at least 70% of the items purchased were on sale or purchased with a coupon.Age range, years 18-28 29-39 40-50 51-61 62 and overMidpoint x 23 34 45 56 67Percent of super shoppers 6% 47% 25% 11% 11%For the 62-and-over group, use the midpoint 67 years. (a) Compute the expected age μ of a super shopper. (Round your answer to two decimal places.)μ = (b) Compute the standard deviation σ for ages of super shoppers.

Chi - square The age distribution of the population in Canada consists of 7.2% inhabitants of ages from 5 years old and below, 13.6% of inhabitants of ages between 6 and 14, 67.1% of inhabitants of ages between 15 and 64, and 12.1% of inhabitants of ages from 65 and above. Lately in a survey conducted on 455 residents in a native-Canadian village in the Northwest Territories (Red Lake Village), it has been counted that there are 47 children with the age of 5 or below, 75 persons with ages between 5 and 14, 288 persons with ages between 15 and 64, and 45 persons with ages of 65 years and above. a)use descriptive statistics for presenting the data b)Use a 5% level of significance to test if there is an agreement between the age distribution in Canada and the age distribution of the residents of Red Lake Village.
Researchers are wondering whether they can predict college GPA with the number of hours studying per week. To test this, they randomly select 8 college students, record their GPA and the number of hours spent studying per week. GPA 2.5 2.7 3.4 3.7 2.7 1.9 2.0 4.0 ID 1 2 3 4 5 6 7 8 Hours studying per week 25.0 27.6 30.2 35.0 31.6 25.6 30.0 40.0 Based on the information in the table above, the researchers compute the regression equation: Y = -0.970 + 0.125 X. Do the researchers have enough evidence to claim that the number of hours studying predicts students' GPA? Based on the analysis, what would be the predicted GPA for someone who studies 30 hours per week? O2.00 O Cannot be predicted. O 1.25 2.78

A hospital has a main campus and three satellite locations. Management wants to reduce waiting time for ER cases. A random sample of 11 ER cases at each location was selected, and the waiting time was measured. (The table of data at the very end may be copied and pasted directly into Excel.) Complete parts (a) through (d) to determine if there is statistical evidence of a difference in the mean waiting times betweeen the four locations. Part 1 a. State the two hypotheses. Choose the correct answer below. A.H0:μ1=μ2=•••=μ4H1:Not allμjare equal (where j=1,2,...,4) B.H0:μ1=μ2=•••=μ4H1:μ1≠μ2≠•••≠μ4 C.H0:μ1=μ2=•••=μ11H1:μ1≠μ2≠•••≠μ11 D.H0:μ1=μ2=•••=μ11H1:Not allμjare equal (wherej=1,2,...,11) b. At the 0.05 level of significance, state the test statistic. (Round to two decimal places to the right of the decimal point as needed.)

Chapter 5, Section 2, Exercise 051 More Information From the Online Dating Survey A survey conducted in July 2015 asked a random sample of American adults whether they had ever used online dating (either an online dating site or a dating app on their cell phone).College-Educated or Not?The survey also asked participants for their level of education, and we wish to estimate the difference in the proportion to use online dating between those with a college degree and those with a high school degree or less. The results are shown in the two-way table below. College High School Total Yes 157 70 227 No 666 565 1231 Total 823 635 1458Table 1: Have you ever used an online dating site or a dating app?

The most obese countries in the world have obesity rates that range from 11.4% to 74.6%. This data is summarized in the following table. Percent of Population Obese Number of Countries 11.4–20.45 32 20.45–29.45 11 29.45–38.45 5 38.45–47.45 0 47.45–56.45 3 56.45–65.45 2 65.45–74.45 1 74.45–83.45 1 (a) What is the best estimate of the average obesity percentage for these countries? (Round your answer to two decimal places.)(b) The United States has an average obesity rate of 33.9%. Is this rate above average or below? (Round your answers to two decimal places.) Since the average for the United Sates is 33.9%, compared to the average obesity rate of %, the United States has an obesity rate % higher than average. (c) How does the United States compare to other countries? (Assume that the United States is included in the data. Assume the other countries in the range 29.45–38.45 have higher obesity than the United States.) 1. The United States has an obesity rate…
