The file scrippsm.txt, available from the textbook website, is a list of 180 numbers which represent the concentration of atmospheric carbon dioxide, in parts per million by volume (ppv), recorded monthly at Mauna Loa from Jan, 1996 to Dec. 2010, taken from the same Scripps study as Computer Problem 8.
a. Carry out a least squares fit of the
b. Use your model to predict the
c. Add the extra term
d. Repeat part (c) using the extra term
e. Add both terms from (c) and (d) and redo parts (a) and (b). Prepare a table summarizing your results from all parts of the problem, and try to provide an explanation for the results. See the website http://scrippsco2.ucsd.edu for much more data and analysis of the Scripps carbon dioxide study.

- 4. Let A {w, e, s, t, f, i, e, l, d, s, t, a, t, e}. (a) How many different words (they do not have to make sense) can you spell with the letters in A? (b) Is your answer from above the same as the cardinality of the powerset of A, i.e. of P(A)? (c) What is |A|?arrow_forwardwhat can the answer be pls helparrow_forward5. How many numbers can you make out of the digits 1, 2, 3, 4, 6 if the rule is that every digit has to be larger than the digit preceding it? For example 124 is ok, 122 is not ok. Every digit can be used only once, but you do not have to use every digit. A tree might help.arrow_forward
