1.
Assume that x has a normal distribution with the specified mean and
standard deviation. Find the indicated probability.
mean=100, stadard dev. = 18
P(x> or = 120) = ?
2. Thickness measurements of anciwnt prehistoric Native
American pot shards discovered in a Hopi village are approximately
normally distributed, with a mean of 4.6 mm and a standard dev. of
1.5mm. For a randomly found shard, find the following
probabilities.
a) The thickness is less than 3.0mm
b) The thickness is more than 7.0mm
c) The thickness is between 3.0mm and 7.0mm
