. It is desired to design 95 confidence intervals for the
ratio between standard deviation of two electroplating lines in a
micro-electro-mechanical system (MEMS) company. If independent
samples of size n1=10 from line-1 has a standard deviation of
S1=0.035 mil and sample size of n2=12 from line-2 has a standard
deviation of s2=0.062 mil, estimate the confidence intervals for
the ratio of standard deviation of line-1 to line-2 (s12/s22)

1) Construct 90%, 95%, and 99% confidence intervals for the
population mean of total daily sales.
2) Run a hypothesis test on the population mean for total daily
sales. Use a hypothesized value of $1600 and test at levels of
significance of 0.01, 0.05, and 0.10. Use both the critical value
and p-value approaches when testing at each level of
significance.
