Question 918898: Based on the report, ‘New Century, Old Disputes’ (Atal, J.P., Nopo,
H., Winder, N., 2009), women hold 33% of the better paid jobs in the
Latin America and Caribbean region. A survey of 100 women reveals
proportion of 0.27.
a) At the 1% alpha level, has the rate changed?
b) What are some of the reasons that could support this low level low
rate in the region?

Ho: p = 0.33 (claim)
Ha: p ≠ .33
n = 100
z = (.27 - .33)/sqrt(.33*.67/100) = -.06/.047 = -1.276
p(z < -1.276) = .10
.10 > .01
At the 1% alpha level, accept claim.
Study does not support that rate has changed.
b) culture, less education, etc
