Answer:
The second packet.
Step-by-step explanation:
First Packet:
Cost of 18 pens = Rs 56
Cost of 1 pen = Rs 56 ÷ 18 = Rs 3.11 (rounded off to 2 decimal places)
Second Packet:
Cost of 8 pens = Rs 45
Cost of 1 pen = Rs 45 ÷ 8 = Rs 5.63 (rounded off to 2 decimal places)
Thus, the second packet is costlier because the cost of 1 pen in the second packet (Rs 5.63) is more than the cost of 1 pen in the first packet. (Rs 3.11)

This symbol indicates the Population Standard Deviation of the data. Standard deviation means how much variation or dispersion is there in our data. Squaring of standard deviation gives us Variance which is denoted by the symbol
.
Formula for Population Standard deviation (
) is =
,
where
= each value from our list of data
= Population mean of data
N = Number of observations in our data
Standard deviation can never be negative and it is very much sensitive to outliers in our data.
