To test a customer’s internet connection, a tech records how long it takes five different websites to load (in seconds). the times are 4.5, 3.8, 2.9, 3.2, and 2.3. what is the average (mean)?

14.86

Step-by-step explanation:

4.5+ 3.8+ 3.2 +2.3=16.7 divided by 5 which I got from how many numbers I added =14.86

3.34 seconds

4.5+3.8+2.9+3.2+2.3=16.7

Then I divided the total by the number of times 5/16.7=3.34 seconds

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

both equations and proportions are better.
