Question

The mean of a continuous data with number of terms 40 is 35. If the class 15-25 with frequency 6 is added to the data find the new mean​

Answer 1

Step-by-step explanation:

Given The mean of a continuous data with number of terms 40 is 35. If the class 15-25 with frequency 6 is added to the data find the new mean  

• Given Mean = sum of terms / number of observations
• Now the mean of 40 observations is 35
• Number of observations = 40
• Mean = 35
• We know that Total = mean x number of observations
•                               = 35 x 40
•                                 = 1400
• If 6 is added to each of the 40 observations, then sum of the values will increase by 40 x 6 = 240
• New total = 1400 + 240
•                = 1640
• Now New Mean = New total / Number of observations
•                         = 1640 / 40
•                       = 41

Therefore New Mean is 41
