Wynn needs to find the center of the data set shown on the dot plot. The dot plot has ___15__ dots. The dot plot has ___7___dots to the left of the center and dots to the right of the center. The center of the data set is 8

We have assumed that the dot plot has 15 dots for the purpose of solving this case.

Step-by-step explanation:

The center of the dot plot is obtained by subtracting 1 from the total dots and dividing the result by 2.

The center of data is a single number that summarizes the entire data set.  It is called the Median.  The median represents the midpoint value of a data set, where the values are arranged in ascending or descending order.  Unlike the mean, the median can be used to find the center of data when the numbers in the data set contain one or more outliers.

It is one of the measures of central tendencies and the most accurate measure for that matter.

answer is  

a.

p = 78

step-by-step explanation:

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
