Question

Suppose certain coins have weights that are normally distributed with a mean of 5.517 g and a standard deviation of 0.055 g. A vending machine is configured to accept those coins with weights between 5.427 g and 5.607 g

**a. If 260 different coins are inserted into the vending
machine, what is the expected number of rejected
coins?**

**The expected number of rejected coins is? (Round to the
nearest integer.)**

Suppose certain coins have weights that are normally distributed
with a mean of 5.159 g and a standard deviation of 0.079 g. A
vending machine is configured to accept those coins with weights
between 5.029 g and 5.289 g. If 270 different coins are inserted
into the vending machine, what is the probability that the mean
falls between the limits of 5.029 g and 5.289 g?

3. Weights of quarters are normally distributed with a mean of
5.67 g and a standard deviation of 0.06 g. Some vending machines
are designed so that you can adjust the weights of quarters that
are accepted. If many counterfeit coins are found, you can narrow
the range of acceptable weights with the effect that most
counterfeit coins are rejected along with some legitimate
quarters.
3. a) If you adjust your vending machines to accept
weights between 5.60 g and 5.74...
