Question
A labor statisticIan claims that 6% of the labor forces will be laid off likely to pandemic impact. In a random sample of 547 employees, 44 of them will be likely to be laid off.
- if you go against the claim, what is the P-value of the test? (use StatCrunch)

Transcribed Image Text:3. A labor statisticlan claims that 6% of the labor
forces will be laid off likely to pandemic
impact. In a random sample of 547 employees,
44 of them will be likely to be laid off.
A. What is the probability of the case that
44 out of 547 will be likely laid off?
B. What is the probability of the case that
more than 44 out of 547 will be likely laid
off?
C. What probability distribution you used for
A and B ?
D. You walk in a city and ask people if they
will be likely laid off. What is the
probability that on the 10th people you
asked was the first instance who
answered "yes"?
E. What probability distribution you used for
D?
F. If you don't trust its claim, what is the
Ho, and what is the Ha ?
G. If you support its claim, what is the Ho,
and what is the Ha ?
H. f you go against the claim, what is the P-
value of the test? (use StatCrunch)
1. Giving the level of significance a = 0.01,
can we reject the claim?
J. Giving the level of significance c = 0.90,
а
what is the confidence interval of the
population proportion ? (use StatCrunch)
