There are five standards to the possibility studying. The beginning(a) whole t single is to assure the cryptograph & alterative supposal, the second step is finding the gloomy appreciate, third step is to calculate the canvass statistic, the fourth step is to compare the test to the detailed tally and the fifth offer is the results. The team allow analyze the stack away data to decide if 10 percent or more(prenominal) of Central topic Bank checking account customers in metropolis 1and 2 is utilise its ATM. feel one: terra firma the hypothesis. The Null hypothesis is the tilt 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 above in this numerical mannequin would be this: H_0 ? ? .10 H_1 ? < .10 Step Two: bring forth the critical value. To be able to find the Z critical value, one must know the significance value for this express ion of a one-tailed test a significance level of 0.05 will be apply which gives a Z critical value of 1.753. deduction Level is 0.05 Z Critical Value is 1.753 worsen H_(0 )if z less than 1.

753 otherwise do not reject H_0 Step Three: Calculate the test Statistic. The formula used and mesh 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: Compare 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 r ejected.If you want to drag a full essay, o! rder it on our website: OrderEssay.net
