(c) 52.2
(d) 53.2​

Answer 1

Answer:

54.5

Step-by-step explanation:

Mean of 10 observations = 50

Sum of 10 observations = 50×10

                                        =500

94 misread as 49

Correct sum of 10 observations = 500 - 49 + 94

                                                     = 451 + 94

                                                     = 545

Correct mean of 10 observations = 545/10

                                                       = 54.5
