Eighteen per cent of multinational companies provide an allowance for personal long- distance calls for executives living overseas. Researchers want to test the claim that an increasing number of companies are providing an allowance for personal long-distance calls to these executives to ease the burden of living away from home. To test this claim, a new study is conducted by randomly sampling 376 multinational companies. Twenty two per cent of these surveyed companies are providing an allowance for personal long-distance calls to executives living overseas. The test statistic and p-value for the test is 2.02 and 2.17% respectively. Which of the following is the correct interpretation of the p-value? AIf the true proportion of multinational companies that provide an allowance for personal long-distance calls for executives living overseas is 18%, then 2.17% of the time we would expect a sample proportion at least as large as the one we actually got.selectedBIf the sample proportion of multinational companies that provide an allowance for personal long-distance calls for executives living overseas is 18%, then 2.17% of the time we would expect a sample proportion at least as small as the one we actually got.CIf the true proportion of multinational companies that provide an allowance for personal long-distance calls for executives living overseas is 18%, then 2.17% of the time we would expect a sample proportion at least as small as the one we actually got.DIf the sample proportion of multinational companies that provide an allowance for personal long-distance calls for executives living overseas is 18%, then 2.17% of the time we would expect a sample proportion at least as large as the one we actually got.SUBMIT

Increasingly, American businesses requiring customer service phone lines have been utilizing overseas companies that can provide these services at extremely reduced rates.  Toll-free calls are routed to countries like India, where low-paid workers have been trained to deal with most of the typical problems consumers have with their credit cards, online services, and computer equipment.  Since the companies using these overseas call centers are saving so much money, they will undoubtedly show higher profits than companies that do not.Which of the following, if true, most seriously weakens the argument?(1 Point)There is strong competition among overseas call centers to provide the most comprehensive services at the lowest rates.Consumers opposed to exporting American jobs are willing to pay more for goods and services from companies that don’t engage in this practice.Certain banking services cannot be outsourced, since this would require the release of customer financial data.Because offshore telephone customer service companies provide only these services, they can train their employees more thoroughly than American companies could.Some American companies send their own employees overseas to train the call center personnel in their particular business.

A survey was conducted in five countries. The percentages of respondents whose household members own more than one personal computer, laptop, notebook or iPad are as follows:AustraliaNew ZealandChinaJapanSouth Korea53%48%38%54%49%Suppose that the survey was based on 500 respondents in each country.a) At the 0.05 level of significance, determine whether there is some significant difference in the proportion of households in these countries who own more than one computer (personal computer, laptop, notebook or iPad). Do the calculations first manually and then in R.b) Find the approximate p-value of the test in (a) from the relevant statistical table.

A company decided to test the hypothesis that the average time a company’s employees are spending to check their private e-mails at work is more than 9 minutes. A random sample of 50 employees were selected and they averaged 9.6 minutes. It is believed that the population standard deviation is 2.5 minutes. The α is set to 0.05. The p-value for this hypothesis test would be __________.

The marketing manager for a home mobility aids needed more information about the age profile of potential customers. The manager predicts that the average age of customers is greater than 70 years.
