In a different shelter, a random sample of dogs’ ages was taken
and the sample
mean was χ = 7.4 years. The standard deviation for the sample was
2.53 years. At
α = 0.05 , test the claim that there is a difference between the
ages of dogs at the two
pet shelters.

's scores, If three points were added to every score in this
distribution, what would be the new mean? If three points were
added to every score in this distribution, what would be the new
standard deviation. Remember, you have already calculated
population standard deviation in a previous problem. This problem
requires two answers.

A researcher believes that 7% of pet dogs in Europe are
Labradors.
If the researcher is right, what is the probability that the
proportion of Labradors in a sample of 590 pet dogs would differ
from the population proportion by more than 3%? Round your answer
to four decimal places.

A researcher is interested in whether the likeability of a
crying woman is affected by the viewer’s knowledge of the woman’s
occupation. Twenty participants were shown a video of a woman
crying and were asked to rate her likeability on a scale from 1
(not very likable) to 10 (highly likable). Prior to viewing the
video,...

A researcher believes that 8% of pet dogs in Europe are
Labradors. If the researcher is right, what is the probability that
the proportion of Labradors in a sample of 630 pet dogs would be
greater than 7%? Round your answer to four decimal places.
My question is since the z table is 0.925 would I add up both
scores and then divide by two? Or would I just round up?
