practice problems of chapter 10 I will start with |
|
|
|
3 |
|
00:00:29,350 --> 00:00:34,410 |
|
number 67 and this type of questions just multiple |
|
|
|
4 |
|
00:00:34,410 --> 00:00:42,030 |
|
choice it says when testing p1 minus p2 equals zero so |
|
|
|
5 |
|
00:00:42,030 --> 00:00:48,010 |
|
we are testing p1 minus p2 equals zero so |
|
|
|
6 |
|
00:00:48,010 --> 00:00:54,490 |
|
we are testing p1 minus p2 equals zero |
|
|
|
7 |
|
00:00:54,490 --> 00:01:01,430 |
|
it asks about the value of p for this test now the value of p |
|
|
|
8 |
|
00:01:01,430 --> 00:01:03,750 |
|
for this test in this case we have two tests |
|
|
|
9 |
|
00:01:03,750 --> 00:01:05,010 |
|
related so to find the value of p we should study the programs |
|
|
|
10 |
|
00:01:05,010 --> 00:01:09,830 |
|
the value is negative |
|
|
|
11 |
|
00:01:09,830 --> 00:01:15,170 |
|
the test is two-tailed |
|
