#In the previous problem, you wrote a function that would #convert text like "abcd efgh ijkl" into "AbCd eFgH IjKl". # #In the previous problem, you could assume the original #string would be all lower-case, with no punctuation. # #Revise your function so that it no longer makes these #assumptions. It should leave any punctuation marks or #numerals unchanged, and it should change the case of #every letter at an even index. That means if the letter #is initially uppercase, it should be converted to lower #case. # #For example: mock("Abcd. Efgh.. Ijkl!") would return #"abCd. efGh.. IJkL!". The even-index letters (A, C, E, g, #j, l) changed case, all other characters were unchanged. # #HINT: Lowercase letters always have an ordinal between #97 ("a") and 122 ("z"). Uppercase letters always have an #ordinal between 65 ("A") and 90 ("Z"). #Write your function here!

Using the artofstat website, run a permutation test to see if there is a difference in the mean amount of time spent on emails per day between in state and out of state students. (make sure to generate 10,000 permutations.) in state students: 2 3 3 6 2 1 1 5 3 2.5 out of state students: 1 2 2 1 2 1 4 3 9 1 10 1 3 what is the p-value?

Agood flowchart alludes to both the inputs and outputs you will need to receive and give to the user. true or false?

Write a modular program (no classes yet, just from what you learned last year), that allows two players to play a game of tic-tac-toe. use a two-dimensional char array with 3 rows and 3 columns as the game board. each element of the array should be initialized with an asterisk (*). the program should display the initial board configuration and then start a loop that does the following: allow player 1 to select a location on the board for an x by entering a row and column number. then redisplay the board with an x replacing the * in the chosen location. if there is no winner yet and the board is not yet full, allow player 2 to select a location on the board for an o by entering a row and column number. then redisplay the board with an o replacing the * in the chosen location. the loop should continue until a player has won or a tie has occurred, then display a message indicating who won, or reporting that a tie occurred. player 1 wins when there are three xs in a row, a column, or a diagonal on the game board. player 2 wins when there are three ox in a row, a column, or a diagonal on the game board. a tie occurs when all of the locations on the board are full, but there is no winner. input validation: only allow legal moves to be entered. the row must be 1, 2, or 3. the column must be 1, 2 3. the (row, column) position entered must currently be empty (i.e., still have an asterisk in it).
