Answer:
33% is the correct answer I took the test!
Step-by-step explanation:
mark me brainliest!!
I believe the correct option is C.
Previous crime rate = c incidents per 1,000 people
Reduction in crime rate after batman brought the joker to justice = 12%
Hence, new crime rate (per 1,000 people) would be = c - 12%×c
⇒ New crime rate (per 1,000 people) would be = c - 0.12×c
⇒ New crime rate (per 1,000 people) would be = 0.88×c
Hence, now the crime rate is 0.88×c per 1,000 people.
Step-by-step explanation:
The data is already in ascending order.
The lower half of the data (120, 140, 160)
has the median 140.
180 is the median of the entire data.
The upper half of the data (200, 220, 240)
has the median 220.
Interquartile Range = 220 - 140 = 80.
Answer:
The mean is 39
The median is 42
Step-by-step explanation:
The median is the best measure of center for the above data because half of the values are less than the median and half of the values are more than the median. It's probably the best measure of center to use in a skewed distribution.
The measure of variability is the range because is the simplest measure of variability to calculate but can be misleading if the dataset contains extreme values.
The variability is 67.25
This is how I did it
