Hello student, an economic professor is interested in finding the mean hour work by the ise student in a week as a part -time or full -time job.
00:11
To accomplish this, the professor randomly selected 240 students.
00:15
The given information is, professor selected 240 students randomly.
00:21
And it was found that the distribution is right skewed.
00:24
The distribution is right skewed.
00:29
And the uni model, the mean was 8 hour and standard deviation is equal to 4 hour.
00:39
Match the condition assumption below to the correct description.
00:43
Then first, uh, assumption or the condition is 240 isu student is less than the 10 % of all isu student.
00:52
Then this is the very important condition when the sampling without replacement.
00:58
And this condition helps to ensure that the sample is good representative of population.
01:13
And the second is, the second condition is our sample size of the 240 is large enough...
