df = (number of rows -1)(number of columns) = (4-1)(3-1)
3.1 2 - Test of Independence (15 pts)
Perform 5 step Hypothesis tests {H0 : Hotels and reason for not returning are independent -not related VS. H1: Hotels and reasons are not independent – related} using = 0.05 and Minitab output.
To get the Minitab output (refer Figure 10 page 411 too), click File -> Open Worksheet and select open PalmHotels data file to the worksheet; select Stat -> Tables -> 2Chi -Square Test (two-way table in worksheet), In the 2 - Test dialog box, enter the names of the column 1 to 3 in the columns containing the table and click Ok. Minitab generates output on the session window, refer the Minitab output in the right side of Figure 10 page 411
From the Minitab output, use the 2 (Chi-sq) and p-Value to perform 5 step hypothesis tests as shown in the Summary for Block 3 file in Summary & Formulas Module posted on D2L, and submit Minitab output with Hypothesis tests using X2 and p-value, use = 0.05.
Explanation / Answer
You already given minitab output.
From the above output there is p-value <0.05 we reject null hypothesis. We conclude that Hotels and reasons are not independent – related}
Hope this will be helpful.
