Final Answer: The values of p^ and q^ are 0.559 and 0.441 respectively.

Steps

Step 1 :Given that the total number of trials, n = 145 and the number of successful outcomes, X = 81.

Step 2 :The sample proportion, p^, is calculated by dividing the number of successful outcomes (X) by the total number of trials (n).

Step 3 :So, p^ = Xn = 81145 = 0.5586206896551724.

Step 4 :The proportion of unsuccessful outcomes, q^, is calculated as 1 - p^.

Step 5 :So, q^ = 1 - p^ = 1 - 0.5586206896551724 = 0.4413793103448276.

Step 6 :Rounding these values to three decimal places, we get p^ = 0.559 and q^ = 0.441.

Step 7 :Final Answer: The values of p^ and q^ are 0.559 and 0.441 respectively.
