1. Shards of clay vessels were put together to reconstruct rim diameters of the original ceramic vessels found at the Wind Mountain archaeological site. A random sample of ceramic vessels gave the following rim diameters (in cm): 15.9 13.4 22.1 12.7 13.1 19.6 11.7 13.5 17.7 18.1 Compute an 80% confidence interval for the population mean µ of rim diameters for such ceramic vessels found at the Wind Mountain archaeological site. a. Write the formula you will be using in the space below (1 point) b. Identify all corresponding values associated with your symbols in the space below (2 points) c. Plug in your values and show your work in the space below (3 points) d. Sketch your distribution, identify your endpoints and label them, shade the area in which your population mean would fall (1.5 points) e. Interpret your results within the context of the problem (1.5 points)

Question #1
Three-circle, red-on-white is one distinctive pattern painted on
ceramic vessels of the Anasazi period found at an archaeological
site. At one excavation, a sample of 163 potsherds indicated that
74 were of the three-circle, red-on-white pattern. Find a point
estimate p̂ for the proportion of all ceramic potsherds at this
site that are of the three-circle, red-on-white pattern. (Round
your answer to four decimal places.)
Compute a 95% confidence interval for the population proportion
p of all ceramic...

1-1) Arrange three cups filled with water. Put cold water in the
first cup together with an ice cube, put hot water (not too hot for
your hand) in the second cup and have the third cup at body
temperature. Now, put one hand in the cold water and the other hand
in the hot water for half a minute or so then put them both in the
lukewarm cup. What did you experience? Decide if you think that
your...

1. There were 2 major shocks to the US economy in 2007, which
together lead to a severe economic slowdown in 2008. One shock was
related to oil prices; the other was related to the housing market.
This question analyzes the effect of these two chocks on GDP using
the AD/AS framework.
a) Draw typical AD and AS supply curves. Label the axis real GDP
and aggregate price level. Label the equilibrium quantity Q1 and
price P1. Data taken from...

1. What would happen if diethyl ether were put in the column
first instead of petroleum ether?
2. The recrystallization lab required you to purify naphthalene
which contained a small portion of fluorenone. Could you use column
chromatography to purify the same mixture? Would the selection of
solvents be different from those used in this lab?
