Dear mam...Ur explanation is really awesome..I was getting so worried about this topic since 2days..after viewing ur video I had a clear explanation..I hope I will do my exams good..
Depending upon the alternate hypothesis we fix the test type. If alternate hypothesis has the not equal to then we go for two tail test. If the alternate hypothesis has inequalities like less than , greater than then we go for one tail test
@@kanimozhij7222 No ma not like that. Comparison can be of any two things.one population and one sample or two samples. but we have to observe the question . If they are asking a specific solution live greater than or less than then we choose alternative hypothesis as less than or greater than and so one tail test.
I hv done both ug and pg in correspondence..preparinv for pgtrb...really ur videos are so much useful ..please mam..if possible start class in you tube for pgtrb...so many people are preparing..kindly consider this..
Mam we can apply the two tailed test for all types of problems ...or need to apply single tailed test mam.....if I apply two tail test in board exam means shall I get full mark mam
In a sample of marathon race times, the mean time is 4 hours, and the standard deviation is 30 minutes. If you set the Z-score threshold to 2, which race times would be considered outliers? Times above 4 hours and 45 minutes Times below 3 hours and 30 minutes Times above 4 hours Times below 2 hours and 45 minutes 2.Setting the p-level at 0.01 increases the chances of making Type II error All of the above Type III error Type I error
