A coin is flipped. If a heads is flipped, then the coin is flipped 2 more times and the
number of heads flipped is noted; otherwise (i.e., a tails is flipped on the initial flip)
then the coin is flipped 3 more times and the result of each flip (i.e., heads or tails)
is noted successively. How many possible outcomes are in the sample space of this
experiment?

Q:
Las enfermeras no solo influyen en los demás durante su labor cotidiana sino que
poseen habilidades expertas en el arte de la persuasión, un proceso que implica
relaciones y negociación. Persuadir a una persona mayor que padece demencia para
que se duche, o a un niño para que coopere mientras se le vacuna, o a sus padres
para permitir la vacunación, son ejemplos de cómo el poder de persuasión en acción
ayuda a negociar un resultado deseable para ambas partes. La esfera de influencia de
las enfermeras, enfermeros como profesionales sanitarios va más allá de las
personas, las familias, los grupos y las comunidades con los que trabajan puesto que
se extiende por todo el sector de la salud hasta llegar a los colegas de enfermeria y
obstetricia, así como a los colegas médicos, de profesiones de salud afines y a
quienes tienen responsabilidades politicas, de gestión y fiscales.
En el contexto de salud la persuasión es

Q:
Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain.
In 1965 , researchers used random digit dialing to call 1200 people and ask what obstacles kept them from
attending sporting events.
What type of sampling was used?
A. Systematic sampling was used, since phone numbers were selected from a list using a fixed interval
between phone numbers.
B. Convenience sampling was used, since the 1200 phone numbers that were easiest to reach were selected.
C. Simple random sampling was used, since each number had an equal chance of being dialed, so all
samples of 1200 phone numbers had an equal chance of being selected.
D. Cluster sampling was used, since the phone numbers were divided into groups, several groups
were selected, and each number in those groups was called.
What potential sources of bias were present, if any? Select all that apply.
\( \square \) A. Individuals may have refused to participate in the sample. This may have made the sample less
representative of the population.
\( \square \) B. Individuals may have not been available when the researchers were calling. Those individuals that were
available may have not been representative of the population.
\( \square \) c. If there was a regular pattern to the numbers dialed, it is possible for the sample to not have been
representative of the population.
