Answer:
Unemployment (August) = 35'222/634'512 ≈ 0.0555 ≈ 5.55%
Employed (August) = 634'512-35'222 = 599'290
Labor force (September) = 634'512-156'518 = 477'994
Employed (September) = 599'290-206'024 = 393'266
Unemployed (September) = 477'994-393'266 = 84'728
Unemployment (September) = 84'728/477'994 ≈ 0.177 ≈ 17.7%

Answer:
29.5+/-1.11
= ( 28.39, 30.61)
Therefore, the 90% confidence interval (a,b) =( 28.39, 30.61)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 29.5
Standard deviation r = 5.2
Number of samples n = 59
Confidence interval = 90%
z-value (at 90% confidence) = 1.645
Substituting the values we have;
29.5+/-1.645(5.2/√59)
29.5+/-1.645(0.676982337100)
29.5+/-1.113635944529
29.5+/-1.11
= ( 28.39, 30.61)
Therefore, the 90% confidence interval (a,b) =( 28.39, 30.61)
