Analyze the residuals of a linear regression model and select the best response.
yes, the residual plot does not show a curve
no, the residual plot shows a curve
yes, the residual plot shows a curve
no, the residual plot does not show a curve
I answered, "No, the residual plot shows a curve." (and this was incorrect). I am not sure why I keep getting these wrong when the answer seems obvious. Please help me understand what the yes and no references in the answer.
Design a Turing Machine recognizing each of the following languages and draw its state diagram.
Note that the transition functions of the Turing Machine must be in the format of “a → b,L/R", namely the machine
reads single symbol a from the tape, writes single symbol b to the cell to replace a, and then goes to either left L or
right R. You will receive 0 point if you do not follow this instruction.
(1) {w|w=a²b³, n ≥ 0}
(2) {w|w=a'b³,i0}
(3) {w|w a'bick,i
Design a PDA recognizing each of the following languages and draw its state diagram.
Note that the transition function must be in the format of “a, b →c", namely we can only push/pop one symbol
into/from the stack one time upon one input symbol. You will receive 0 point if you push/pop multiple symbols
into/from the stack one time upon one input symbol.
(1) {w|wa"b", n is odd}
=
(2) {w|w=w², length of w is odd and Σ = {a,b} }
(3) {w|w= = a²b²n, n ≥1 }
(4) {w|w=
=a^bn+mcm, n≥0, m ≥ 1 }
(5) {w|w=a²b³n, n≥0}
(6) {w|w= = a¹³, n ≥ 1, m≥ 1 and n‡m }
Hint: two cases: n > m and n

- You have been hired as an intern to run analyses on the data and report the results back to Sarah; the five questions that Sarah needs you to address are given below. please do it step by step on excel Does there appear to be a positive or negative relationship between price and screen size? Use a scatter plot to examine the relationship. Determine and interpret the correlation coefficient between the two variables. In your interpretation, discuss the direction of the relationship (positive, negative, or zero relationship). Also discuss the strength of the relationship. Estimate the relationship between screen size and price using a simple linear regression model and interpret the estimated coefficients. (In your interpretation, tell the dollar amount by which price will change for each unit of increase in screen size). Include the manufacturer dummy variable (Samsung=1, 0 otherwise) and estimate the relationship between screen size, price and manufacturer dummy as a multiple…arrow_forward(a) (b) (c) (d) de unique?
