Given data is as follows
Day | # of baby |
Monday | 123 |
Tuesday | 116 |
Wednesday | 92 |
Thursday | 92 |
Friday | 104 |
Saturday | 96 |
Sunday | 77 |
The proportion of new born babies on each day are obtained by dividing number of new born babies on a particular day by the total number of new babie on all days
Here the total number of babies on all days = 123 + 116 + 92 + 92 + 104 + 96 + 77
= 700
Proportion of new born babies on Monday = 123 / 700
= 0.175714
Proportion of new born babies on Tuesday = 116 / 700
= 0.165714
Proportion of new born babies on Wendesday = 92 / 700
= 0.131429
Proportion of new born babies on Thursday = 92 / 700
= 0.131429
Proportion of new born babies on Friday = 104 / 700
= 0.148571
Proportion of new born babies on Saturday = 96 / 700
= 0.137143
Proportion of new born babies on Sunday = 77 / 700
= 0.11
The proportions along with the number of new born babies are represented in the table below
Day | # of baby | Proportion |
Monday | 123 | 0.175714 |
Tuesday | 116 | 0.165714 |
Wednesday | 92 | 0.131429 |
Thursday | 92 | 0.131429 |
Friday | 104 | 0.148571 |
Saturday | 96 | 0.137143 |
Sunday | 77 | 0.11 |
As clearly visible from the above table, the porportions of new born babies on each day of the week are different
Only on Wednesady and Thursday, the proportions of new born babies are same
