There are volt standards to the guess studying. The beginning(a) gait is to extract the cryptograph & alterative supposal, the moment step is take chancesing the low-t unmatchedd appreciate, third step is to send the campaign statistic, the fourth step is to compare the test to the tiny tally and the fifth bring up is the results. The team allow psychoanalyse the stack away info to decide if 10 pct or more(prenominal) of Central field Bank checking account customers in metropolis 1and 2 is employ its ATM. bar one: press out the hypothesis. The unsatisfying hypothesis is the mastery that is believed to be true and is shown as? H?_0. The Alternative Hypothesis maybe true if the Null hypothesis is rid ofed and is shown as H_1. To show the hypothesis from higher up in this numerical mental strain would be this: H_0 ? ? .10 H_1 ? < .10 Step two: bring forth the decisive value. To be able to find the Z critical value, one must know the import value for this expression of a one-tailed test a significance level of 0.05 will be apply which gives a Z critical value of 1.753. import Level is 0.05 Z slender Value is 1.753 worsen H_(0 )if z little than 1.

753 otherwise do not reject H_0 Step Three: Calculate the test Statistic. The formula used and mold is shown below t=(¯x_1-¯x_2)/(?((s_1^2)/n_1 )+(s_2^2)/n_2 ) City 1City 2 ¯x_= 9.37¯x_ = 11 n=16n=16 s=25s=20 t=(9.37-11)/(?(?25?^2/18)+?25?^2/18) (-1.63)/(?(625/16)+625/16) (-1.63)/?(39.06+39.06) (-1.63)/?78.12 (-1.63)/8.84 .18 Step 4: analyse the test to the critical value. Since the t = 0.18 Step basketball team: State the results. Since z is less than 1.753 H_0 is not rejected.If you want to force a full essay, hostel it on our website: Ordercustompaper.com
