Answer:
Step-by-step explanation:
Let k represent the price in dollars at which Nita will buy the keyboard.
We have been given Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under $50.
This means that Nita will buy the computer, when its price (k) is less than $50. We know that sign < represents less than.
We can represent our given information in an inequality as:
Therefore, our required inequality would be .
Answer:
And if we analyze the info provided we have 500 values
Tails: 160,165,167,171,175,...,268,269,269,269,270,270
So as we can see on the tails any values is <150 or >310 so then for this case we cannot consider as outliers any of the values on the tails of the distribution.
Step-by-step explanation:
For this case we have the 5 number summary
(160,210,220,250,270)
So then we have:
minimum = 160 , Q1 = 210, Q2= Median=220, Q3 = 250, Max=270
If we find the interquartile range we got:
For this case we need to find the lower and upper limit with the following formulas:
And if we analyze the info provided we have 500 values
Tails: 160,165,167,171,175,...,268,269,269,269,270,270
