The Wind Mountain archaeological site is located in southwestern New Mexico. Wind Mountain was home to an ancient culture of prehistoric Native Americans called Anasazi. A random sample of excavations at Wind Mountain gave the following depths (in centimeters) from present-day surface grade to the location of significant archaeological artifacts†. Please show all steps to get answer. 85 45 120 80 75 55 65 60 65 95 90 70 75 65 68
(a) Use a calculator with mean and sample standard deviation keys to find the sample mean x and sample standard deviation s. (Round your answers to one decimal place.)
x = cm
s = cm
(b) Compute a 90% confidence interval for the mean depth μ at which archaeological artifacts from the Wind Mountain excavation site can be found. (Round your answers to one decimal place.)

Wind Mountain is an archaeological study area located in
southwestern New Mexico. Potsherds are broken pieces of prehistoric
Native American clay vessels. One type of painted ceramic vessel is
called Mimbres classic black-on-white. At three different sites,
the number of such sherds was counted in local dwelling
excavations.

The Wind Mountain archaeological site is in southwest New
Mexico. Prehistoric Native Americans called Anasazi once lived and
hunted small game in this region. A stemmed projectile point is an
arrowhead that has a notch on each side of the base. Both stemmed
and stemless projectile points were found at the Wind Mountain
site. A random sample of n1 = 55 stemmed
projectile points showed the mean length to be
x1 = 3.00 cm, with sample standard deviation
