I only need B1-5
Recent research commissioned by Vodafone suggests that older workers are the happiest employees (BBC News, July 21, 2008). The report documents that 70% of older workers in England feel fulfilled, compared with just 50% of younger workers. A demographer believes that an identical pattern does not exist in Asia. A survey of 120 older workers in Asia finds that 75 feel fulfilled. A similar survey finds that 58% of 210 younger workers feel fulfilled. (You may find it useful to reference the appropriate table: z table or t table)
At the 5% level of significance, test if older workers in Asia feel less fulfilled than their British counterparts.
a-1. Select the null and the alternative hypotheses.
multiple choice 1
-
H0: p = 0.70; HA: p ≠ 0.70
-
H0: p ≤ 0.70; HA: p > 0.70
-
H0: p ≥ 0.70; HA: p < 0.70
a-2. Calculate the sample proportion. (Round your answer to 3 decimal places.)
a-3. Calculate the value of test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
a-4. Find the p-value.
multiple choice 2
-
p-value ≤ 0.01
-
0.01 < p-value ≤ 0.025
-
0.025 < p-value ≤ 0.05
-
0.05 <p-value ≤ 0.10
-
p-value > 0.10
a-5. What is the conclusion?
multiple choice 3
-
Older workers in Asia feel less fulfilled
-
Older workers in Asia do not feel less fulfilled
At the 5% level of significance, test if younger workers in Asia feel more fulfilled than their British counterparts.

-
H0: p ≥ 0.50; HA: p < 0.50
b-2. Calculate the sample proportion. (Round your answer to 2 decimal places.)
b-3. Calculate the value of test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
b-4. Find the p-value.
multiple choice 5
-
p-value ≤ 0.01
-
0.01 < p-value ≤ 0.025
-
0.025 < p-value ≤ 0.05
-
0.05 < p-value ≤ 0.10
-
p-value > 0.10
b-5. What is the conclusion?
