A researcher wanted to know whether willingness to use online banking systems depends on the age. He performed the survey of 500 people of different ages. It was found that 300 of 500 people that took part in the survey used online banking systems. Of these 300 people, 150 people were under the age of forty. A total of 225 people who took part in the survey were under the age of forty. The data obtained in the study should be summarized in the contingency table below. Using information given above fill in the contingency table below. Is there sufficient sample evidence that the willingness to use online banking system is Independent of the age? Test appropriate hypotheses using level of significance a = 0.01. Age Use of online banking Under 40 40 or more Yes a. Place the values of observed frequencies; row, column and overall totals; and expected frequencies into the table. ( I b. State null and alternative hypotheses. H₂: H₁: c. State the calculated value of test statistic. X = d. State the critical value of test. No %. = e. Decide whether null hypothesis is true and make the conclusions about independence of the variables.
