Part 2 Answer the following to summarize the test of the hypothesis that there is no dependence between age and regularity of email use. For your test, use the 0.10 level of signicance. (a) Determine the type of test statistic to use. X E) r? Type of test statistic: [Choose one) V (b) Find the value of the test statistic. (Round to two or more decimal places.) (c) Find the p-value. (Round to three or more decimal places.) (d) Can we reject the hypothesis that there is no dependence between age and regularity of email use? Use the 0.10 level of signicance. 0 Yes O No To determine a target audience for a new email package, a computer company surveyed a large random sample of potential customers, asking each whether helshe uses email on a regular basis. (The company considered "a regular basis" to be at least three times a week.) The data, as summarized in the contingency table below, were classied according to two variables: the age of the respondent ("under 18", "18-35", "3654", "55+") and regularity ofemar'l use ("on a regular basis" or "not on a regular basis"). Each cell of the table contains three numbers: the rst number is the observed ce|| frequency (fa); the second number is the expected cell frequency (fE) under the assumption that there is no dependence between age and regularity of email use and the third number is the following value. 2' 2 (f0 VGE) (Observed cell frequencyExpected cell frequency) fE _ Expected cell frequency The numbers labeled "Total" are totals for observed frequency. Part 1 2 (fafa Fill in the missing values in the contingency table. Round your expected frequencies to two or more decimal places, and round your values to f3 three or more decimal places.
