Answer:
It is the first one and for number 2 is 160 people total
2x=80
4x=160
Answer:
Data set B would have flatter distribution with more data in each tail.
Step-by-step explanation:
We are given the following in the question:
Data set A has a smaller standard deviation than data set B.

Standard Deviation:
- It is a measure of dispersion of data.
- It tells us about how much the data deviates around the mean.
- It tells us about the overall deviation of the data from the mean.
- The standard deviation is small when the data are all close to the mean showing less variation.
- The standard deviation is larger when the data values are farther away from the mean, showing more variation.
Since data A has less standard deviation than data B, then data B has a flatter graphical representation as more of the data are present on the tails.

Multiplying/Dividing a negative to a positive will equal a negative. (N×P=N)
Multiplying/Dividing a negative to a negative will equal a positive. (N×N=P)
Multiplying/Dividing a positive to a positive will equal a positive. (P×P=P)
