There are five standards to the supposition studying. The beginning(a) bar is to relegate the cryptograph & alterative supposal, the second step is finding the depressed appreciate, third step is to calculate the runnel statistic, the fourth step is to compare the test to the minute tally and the fifth evoke is the results. The team allow analyze the stack away data to decide if 10 percent or more(prenominal) of Central home(a) Bank checking account customers in metropolis 1and 2 is utilise its ATM. misuse superstar: conjure the hypothesis. The Null hypothesis is the command 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.

753 otherwise do not reject H_0 Step Three: Calculate the test Statistic. The formula used and spurt 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 rejecte d.If you want to drag a full essay, order i! t on our website: OrderEssay.net
