The following time series tests are performed in R:Box.test(data, lag=20, type="Ljung")adf.test(data)kpss.test(data, null="Trend")kpss.test(diff(data), null="Trend")And the output is given below:Box-Ljung test p-value < 2.2e-16Augmented Dickey-Fuller Test p-value = 0.4301KPSS Test for Trend Stationarity p-value = 0.01KPSS Test for Trend Stationarity p-value = 0.1From the above information, answer the followingquestions.a) What is the value of d, the differencing? (b) The Box-test tests whether the structure of timeseries is worth modeling. (True or False)(No answer given) →c) The Dickey-Fuller test shows that the timeseries is stationary. (True or False) (

in the C++ version please suppose to have a score corresponding with probabilities at the end and do not use the count[] function. Please explain the detail when coding. DO NOT USE ARRAY. The game of Pig The game of Pig is a dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - if the player rolls 1: the player scores nothing and it becomes the opponents turn. 2 - 6: the number is added to the player's turn total and the player's turn continues. hold - The turn total is added to the player's score and it becomes the opponent's turn. This game is a game of probability. Players can use their knowledge of probabilities to make an educated game decision. Assignment specifications Hold-at-20 means that the player will choose to roll…
Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'
