Question

1. a. You want to estimate the mean hourly yield for a process that manufactures an
antibiotic. You observe the process for 50 hourly periods chosen at random, with the
results ?̅= 31 ounces per hour and ? = 3. Estimate the mean hourly yield for the
process using a 90% and 95% confidence interval.

A paired-difference experiment was conducted
to compare the means of two populations:

a. Do the data provide sufficient evidence to indicate
that µ, differs from µz? Test using a = .05.
b. Find the approximate p-value for the test and inter-
pret its value.

Professor Isaac Asimov
was one of the most prolific writers of all time. Prior
to his death, he wrote nearly 500 books during a
40-year career. In fact, as his career progressed, he
became even more productive in terms of the number
of books written within a given period of time.' The
data give the time in months required to write his
books in increments of 100:
Number of Books, x | 100
200
300
400
490
Time in Months, y
237
350
419
465
507
a. Assume that the number of books x and the time in
months y are linearly related. Find the least-squares
line relating y to x.
b. Plot the time as a function of the number of books
written using a scatterplot, and graph the least-
squares line on the same paper. Does it seem to
provide a good fit to the data points?
c. Construct the ANOVA table for the linear
regression.
