00:01
So, in the given question, we are going to assume the s naught as the bag can stand, the bag can stand temperature, temperatures of minus 15 degree fahrenheit.
00:36
So, they have asked us to for this, actually this is the null hypothesis.
00:43
What they are asked us in the question is we have to state the type 1 error and the type 2 error for this thing.
00:50
So, first let us go with the type 1 error, type 1 error.
00:58
So, type 1 error means we will represent the type 1 error with the letter with the greek alphabet alpha.
01:05
So, what is the meaning of this is, it is the type 1 error is the probability of rejecting, it is the probability of rejecting the null hypothesis that is our h naught, when the h naught is actually true, when it is actually true.
01:34
So, this is called as the type 1 error.
01:37
And this type 1 error is stated as the researcher, how it is stated is the researcher concludes, see from this we are going to compare, rejecting the h naught.
01:59
So, what is the h naught in the question? h naught is the bag can stand temperatures of minus 15 degree celsius.
02:05
So, the researcher who is going to reject this h naught.
02:09
So, what he is concluding is the bag cannot stand, at what actually is true is it can stand.
02:19
But the researcher is concluding the bag cannot stand temperatures of minus 15 degree fahrenheit, when what is actually true is when or but you can say, but the bag can stand temperatures of minus 15 degree fahrenheit.
03:11
So, this is one case...
