Sick Days in Bed A researcher wishes to see if the average number of sick
days a worker takes per year is greater than 5. A random sample of 26
workers at a large department store had a mean of 5.2. The standard

researcher's claim at a=0.05? Assume that the variable is normally distributed.

Sample Question
Sick Days in Bed A researcher wishes to see if the average
number of sick days a worker takes per year is greater than 5.
A random sample of 25 workers at a large department store
had a mean of 5.3. The standard deviation of the population is
1.4. Is there enough evidence to support the researcher's claim
at a= 0.01? Assume that the variable is normally distributed. Use
the critical value method with tables.
(a) State the hypotheses and identify the claim with the correct
hypothesis.
(b) Find the critical value(s).
(c) Compute the test value.
(d) Make the decision.
(e) Summarize the results.
Explanation
(a) State the hypotheses and identify the claim with the
correct hypothesis.
The null hypothesis H, is the statement that there is no
difference between a parameter and a specific value. This is
equivalent to H,:µ=5.
The alternative hypothesis H, is the statement that there is a
difference between a parameter and a specific value. In this
case, the average number of sick days is greater than 5. This is
equivalent to H : µ>5.
The problem asks, "Can it be concluded that the average
number of sick days is greater than 5?"
Hence, the claim is the alternative hypothesis.
