An engineer believes that the number of defects on a product he is working on has the Poisson pmf. He collects a sample of 25 and notes the number of defects on each product. The sorted data are 0, 0, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4. Perform a Chi-Square Goodness of Fit test on these data. Take all intermediate computations to four decimal places. What is the numerical value of the test statistic? Express your answer to three decimal places.

An engineer has collected processing times for a certain part as follows: 4 min, 3 min, 2 min, 4 min, 3 min, 14 min. This question is part of a quiz or exam at Arizona State University. No portion may not be posted to any website, photos and screenshots may not be taken, and no portion of it may be printed out. The table for a normal probability plot would be: j xj (j-0.5)/n zj 1 A F K 2 B G L 3 C H M 4 D I N 5 E J O 6 P Q R To 3 decimal places, K = _____ Do any intermediate computations to 4 decimal places.

Question 5 – Write a VBA macro in the box provided that prompts the user to “Enter an InvoiceNumber:”, then uses a loop to count how many times that InvoiceNumber appears in column M across rows 1 to 75. The macro should output the total count using a message box that displays: “The number of line items associated with this Invoice is: [count]”. HINT: You will need to use InputBox for the user’s invoice number. In total, you should have 4 variables: one String, two Range, and one Long. If there are no occurrences, the message box should display 0. [20pts]
