From the summary results, Zamstats indicated that the 2022 Zambian population is 19,610,769. Assume that 35% of the population are not in the labour force. Suppose also that from those in the labour force, 40% are employed. Determine the total number of people who are;a) not in the labour force.b) in the labour force.c) employed.d) unemployed.arrow_forwardthe unemployment rate for 18- to 34-year-olds was reported to be 10.8% (the Cincinnati Enquirer, november 6, 2012). assume that this report was based on a random sample of four hundred 18- to 34-year-olds. a. a political campaign manager wants to know if the sample results can be used to conclude that the unemployment rate for 18- to 34-years-olds is significantly higher than the unemployment rate for all adults. according to the bureau of labor Statistics, the unemployment rate for all adults was 7.9%. develop a hypothesis test that can be used to see if the conclusion that the unemployment rate is higher for 18- to 34-year-olds can be supported.b. use the sample data collected for the 18- to 34-year-olds to compute the p-value for the hypothesis test in part (a). using a 5 .05, what is your conclusion?c. explain to the campaign manager what can be said about the observed level of significance for the hypothesis testing results using the p-valuearrow_forwardHow are quintiles calculated? Select the correct answer below: Calculated using the average of the entire population. Ranks people by age from lowest to highest and divided by five. The totals are then summed to compare to the total income. Quintiles rank the population from the lowest to highest and divides all households into five O groups of equal numbers of people. The totals are then summed to compare to the total income. Ranks the households from largest to smallest and finds the income mode.arrow_forward

Imagine that I wanted to test the proposition that people think older politicians are more trustworthy. I recruited an internet sample of 90 people. Each person was asked to read a short article about a hypothetical political candidate. Random assignment determined whether the subjects were told that candidate was 65 or whether they were told that candidate was 35. After reading the article, all subjects used a 10-point scale to rate the candidate on competence, trustworthiness, and likability. I take the mean values of trustworthiness in each group, perform a difference of means test, and find a test statistic of 1.04. Should I reject the null at the 99% confidence level? Why or why not? What does that mean?arrow_forward
- 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 70 stocks traded on the NYSE that day showed that 31 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3. You use a significance level of α=0.002α=0.002.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…arrow_forward2. Based on past records, it is generally believed that on an average, a typical University of Technology and Applied Sciences, Nizwa student spends about 25 hours in the LRC per week. Recently, the library has been shifted to a new location which is further away from the academic block. As a result, the administration feels that students may be spending less time in the library. Accordingly a random sample of 41 students were selected and the average number of hours they spend in the library came out to be 16.78 with a standard deviation of 5.17. Carry out an appropriate test of hypotheses for the above problem to test whether the shifting of the library has adversely impacted the study time in the population of all students. (You may assume that study times/week approximately follow a normal distribution in the population).arrow_forwardA life insurance company wishes to examine the relationship between the amount of life insurance held by a family and family income.

- A company is considering an organizational change which entails adopting the use of self-managed work teams which they hope will lead to higher levels of employee satisfaction. In order to assess the attitudes of employees of the company towards this change a sample of 250 employees was selected and asked whether they favor the institution of self-managed teams. Three responses were allowed: favor, neutral or oppose. The observed frequency of the results of the survey are shown below: Opinion Type of Job Favor Neutral Oppose Total Hourly Worker 25 40 35 100 Supervision 45 35 20 100 Manager 20 15 15 50 Total 90 90 70 250 Use this data to test the hypothesis that opinion and type of job are independent at the .025 level.arrow_forwardAverage prices (in dollars) were recorded for three types of beverage across all 8 major Australian states and territories.
