Answer 1

Answer:

We have given that data 8 14 20 26 32 38 44 50

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 6

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 6

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=6

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=6

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=638-32=6

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=638-32=644-38=6

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=638-32=644-38=650-44 =6

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=638-32=644-38=650-44 =6So class size will be 6 ( As the difference between two consecutive number is 6 )

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=638-32=644-38=650-44 =6So class size will be 6 ( As the difference between two consecutive number is 6 )Now range of the number = 50 - 8 = 42

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=638-32=644-38=650-44 =6So class size will be 6 ( As the difference between two consecutive number is 6 )Now range of the number = 50 - 8 = 42Total number of data = 8

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=638-32=644-38=650-44 =6So class size will be 6 ( As the difference between two consecutive number is 6 )Now range of the number = 50 - 8 = 42Total number of data = 8So class interval

We have given that data 8 14 20 26 32 38 44 50Difference between two consecutive number is14 - 8 = 620-14 = 626-20=632-26=638-32=644-38=650-44 =6So class size will be 6 ( As the difference between two consecutive number is 6 )Now range of the number = 50 - 8 = 42Total number of data = 8So class interval So class size will be 6 and class interval will be 5.25
