Toledo university indicate that 50 percent of student change major in their first year a sample of 100 student 48 change major in their first year. is there a significant decrease in the proportion of student change major in their first year test at .05 significance level
-----------------------------
Ho: p = 0.50
H1: p < 0.50
---------------------
CV: z = -1.645
Test stat: z(0.48) = (0.48-0.50)/sqrt[0.5*0.5/100] = -0.4
-----------------------
Conclusion: Since the ts is not in the reject interval, do not
reject Ho at the 5% significance level.
