Hi, i'm david and i'm here to help me answer your question.
00:04
Now let me bring up your question here.
00:07
In this question here, we want to perform the hybrid testing.
00:11
Here we have the 54 % of all factor auto accidents.
00:18
And then we will test that claim there.
00:22
So the art note, the proportion equal to the 154.
00:28
And we want to test if the claim there.
00:31
Will be accurate.
00:32
It means that one to test the arch one will be proportion will not equal to the 0154.
00:38
And here we are given the 30 random selected photo accidents, so n equal to the 30.
00:45
And we have x equal to the 14 was caused by driver error.
00:51
So from here, the sum of proportion p .ht equal to x over n, equal to the 14 over 30.
00:59
So get equal to the 0 .4667.
01:08
And then the next time we need to compute the test statistics...
