The five number summary of a dataset was found to be: 47, 54, 67, 69, 70 An observation is considered an outlier if it is below:
1 answer:
Answer:
Below 31.5 or above 91.5
Step-by-step explanation:
Given that the five number summary of a dataset was found to be: 47, 54, 67, 69, 70
This can be written as
Minimum: 347
Quartile Q1: 54
Median: 67
Quartile Q3: 69
Maximum: 7 0
We calculate Inter quartile range as
IQR = Q3-Q1 =
We find an item to be an outlier if it is either below 1.5 IQR from Q1 or above 1.5 IQR from Q3
Here we say an outlier if item is either below
Or above

Answer: 8 cupcakes per box
Step-by-step explanation: "Per box" means in 1 box, so we can rewrite the given statement using fractions as
<em>48 cupcakes/6 boxes</em> = <em>__ cupcakes/1 box</em>.
To find out what goes in the blank, notice that we
have a 1 in the denominator of our second fraction.
So we want to find a fraction that is equivalent
to 48/6 that has a 1 in the denominator.
If we divide the numerator and denominator of 48/6 by 6,
we get the equivalent fraction 8/1 or <em>8 cupcakes/1 box</em>.
So now we have <em>8 cupcakes/1 box = __cupcakes/1 box</em>.
So an 8 must go in the blank which means that the unit rate
for 48 cupcakes in 6 boxes is <em>8 cupcakes per box</em>.
