Q43299 Estatística
       Uma empresa de consultoria realizou um levantamento estatístico para obter informações acerca do tempo (T) gasto por empregados de empresas brasileiras na Internet em sítios pessoais durante suas semanas de trabalho. Com base em uma amostra aleatória de 900 empregados de empresas brasileiras com um regime de trabalho de 44 h semanais, essa empresa de consultoria concluiu que cada empregado gasta, em média, 6 h semanais na Internet em sítios pessoais durante uma semana de trabalho; 50% dos empregados gastam 5 h semanais ou mais na Internet em  sítios pessoais durante uma semana de trabalho; e o desvio padrão do tempo gasto na Internet em sítios pessoais durante o regime de trabalho é igual a 4 h semanais por empregado.

Com base nas informações da situação hipotética acima descrita, julgue os itens a seguir.

Considerando que a probabilidade de um empregado gastar mais do que 8 h semanais na Internet em sítios pessoais durante seu regime de trabalho seja igual a 0,2 e considerando, também, que X seja uma variável aleatória que represente o número de casos de pessoas que gastam mais do que 8 h/semana na Internet em sítios pessoais durante seus regimes de trabalho na amostra aleatória de 900 empregados, o desvio padrão de X será igual ou inferior a 12.

Q43304 Inglês
One frequently overlooked area in planning is technical
reviews and inspections. A technical review requires substantial
preparation on the part of the presenters. Documents must be
published and distributed and presentation material organized and
made into slides or overheads. Practice sessions are conducted by
presenters with an audience of critics to prepare for the review.
The reviewers should read the material, attend the
presentations, and write reports. On large projects with many
reviews and walk-throughs involving many participants, a
substantial number of labor hours can be consumed analyzing
documents, attending meetings, and writing reports. For example,
a system design review for one module or unit can require 150
labor hours. When overlooked, this labor can result in a very
large error in resource and schedule estimation.
Many projects include risk assessment and risk
management as a key part of the planning process and expect the
plan to identify specific risk areas. The plan is expected to
quantify both probability of failure and consequences of failure
and to describe what will be done to contain development risk.
