Answer:

228

Step-by-step explanation:

Given---

Mean of 15 observations = 200

Total Sum of all Observations = 15 × 200

                                               = 3000

On Excluding an Observations,

              The Mean of Remaining 14 Observations is 198.

           Thus, Total Sum of all 14 Observations = 198 × 14

                                                                          = 2772

Excluded Observations = Total of 15 observations - Rest of 14 Observations.

                                     = 3000 - 2772

                                     = 228.

Thus, the Value of the Excluded Observations is 228.

Step-by-step explanation:

Mean of 15 observations = 200

Total Sum of all Observations = 15 × 200

                                              = 3000

On Excluding an Observations,

             The Mean of Remaining 14 Observations is 198.

          Thus, Total Sum of all 14 Observations = 198 × 14

                                                                         = 2772

Excluded Observations = Total of 15 observations - Rest of 14 Observations.

                                    = 3000 - 2772

                                    = 228.

Thus, the Value of the Excluded Observations is 228.
