DV: Aggression (noise) level on a 0–10 scale
Average of Real Housewives groups =
Average of Little People, Big World groups =
Is there a main effect of TV show on aggression? (Yes or no? Then, describe. Use this format: “There is [is not] a main effect for TV show, such that_____________________________”)
Average of insult groups =
Average of no-insult groups =
Is there a main effect of Insult on aggression? (yes or no, then describe. Use this format: “There is [is not] a main effect for Insult, such that_____________________________.”)
Is there an interaction in this set of results? If so, describe it:

The ideal (daytime) noise-level for hospitals is 45
decibels with a standard deviation of 10 db; which is to say,
this may not be true. A simple random sample of 81
hospitals at a moment during the day gives a mean noise level of 47
db. Assume that the standard deviation of noise level is really 10
db. All answers to two places after the decimal.
(a) A 99% confidence interval for the actual mean noise level in
hospitals is...

A vertical scale on a spring balance reads from 0 to 235 N . The
scale has a length of 10.5 cm from the 0 to 235 N reading. A fish
hanging from the bottom of the spring oscillates vertically at a
frequency of 2.65 Hz .
Ignoring the mass of the spring, what is the mass m of
the fish?
Express your answer in kilograms.

The mean noise level of 20 areas
designated as “casualty doors” was 63.1 dBA, and the standard
deviation is 4.1 dBA. The mean noise level for 24 areas designated
as “operating theaters” was 57.3 dBA and the standard deviation was
7.5 dBA. At α = 0.01 can it be concluded that the mean
casualty doors noise level is greater than the mean noise level for
the operational theaters?
