In how many of these 150 days will the light be yellow exactly once? Use the data to make a prediction.Set A: n = 5; x = 10Set B: n = 50; x = 10(a) Suppose the number 32 is included as an additional data value in Set A. Compute x for the new data set. To compute x for the new data set, add 32 to x of the original data set and divide by 6. (Round your answer to two decimal places.) b.)
