I think about a two-sample t-test for independent populations as a special case of an ANOVA where the number of groups is just 2. Given this way of viewing things, you might wonder if we will get the same results pushing data through a two-sample t-test vs. an ANOVA with two groups. Let's find out. Using R, read in the file pi. csv which has 10000 digits of = 3.1415926 We'll compare the digits in the odd indices (3, 4, 5, 2, etc.) with those in the even indices (1, 1, 9, 6, etc.). a. Write code that compares the average digit in odd and even indices using a t-test. Give your t-stat and P-value. (PHNTOM, code] b. Repeat your analysis using an ANOVA. You'll need to figure out how to build a data frame formatted for an ANOVA. Include your F-stat and P-value. (PUNTOM, code] c. What relationship exists between the t-stat and F-stat? Between the P-values? d. The relationship between the t-stat and F-stat suggested by part c is actually the consequence of a relationship between the distributions T. and F By playing around with code in R, find a relationship between these distributions. Include the code that led to your conjecture relating these two distributions. Again, this is a problem where a Google search immediately gives the answer. Resist this temptation; learning is about the journey, not just the destination

Write a pseudocode solution for each of these problems. 1. design a while loop that lets that user enter a number. the number should be multiplied by 10, and the result stored in a variable named product. the loop should iterate as long as product contains a value less than 100. 2. design a do-while loop that asks the user to enter two numbers. the numbers should be added and the sum displayed. the loop should ask the user whether he or she wishes to perform the operation again. if so, the loop should repeat; otherwise it should terminate. 3. design a for loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 100. 4. design a nested loop that displays 10 rows of # characters. there should be 15 # characters in each row. 5. convert this for loop to a while loop. declare integer count for count = 1 to 50 display count end for 6. find the error in the following pseudocode. declare boolean finished = false declare integer value, cube while not finished display โ€œenter a value to be cubed.โ€ input value; set cube = value ^ 3 display value, โ€œ cubed is โ€œ, cube end while
