Answer:
≈ 14.3 hours
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex] = [tex]\frac{17+19+5+17+20+6+16}{7}[/tex] = [tex]\frac{100}{7}[/tex] ≈ 14.3 ( to nearest tenth )
The mean number of hours for watch television last week is 14.3 hours.
1) Mean is calculated using the formula
Mean of data= [tex]\frac{sum of all observation}{total no. of observation }[/tex]
2) Median is calculated based on two conditions:
Case (1) If n, the number of observations, is an even number
Formula: Median of data=[tex]\frac{1}{2} (\frac{n}{2}th term + (\frac{n}{2}+1) th term)[/tex]
Case (2) If n, the number of observations, is an odd number
Formula: Median of data=[tex]\frac{n+1}{2} th term[/tex]
Given :
Sum of the student =[tex]17+19+5+17+20+6+16[/tex] [tex]= 100[/tex]
Total no of student = [tex]7[/tex]
Find :
Mean the mean number of hours ;
Formula :
Mean = [tex]\frac{sum of all observation}{total no. of observation }[/tex]
Mean = [tex]\frac{100}{7}[/tex] = [tex]14.28[/tex] [tex]hr[/tex] = [tex]14.3 hr[/tex]
Nearest tenth of [tex]14.28[/tex] is [tex]14.3[/tex].
Hence , the mean number of hours for these students watch television for last week is 14.3 hours .
