Winter Olympics. If the mean is 20.4 and the standard deviation is 7.9, circle all values that
fall within one standard deviation of the mean.
6, 11, 15, 17, 19, 24, 25, 26, 28, 33
Answer:
You should circle:
15, 17, 19, 24, 25, 26, 28
Step-by-step explanation:
The values x that falls within 1 standard deviation of the mean are those which.
6
|6 - 20.4| = 14.4 > 7.9
6 is not within 1 standard deviation of the mean.
11
|11 - 20.4| = 9.4 > 7.9
11 is not within 1 standard deviation of the mean.
15
|15 - 20.4| = 5.4 < 7.9
15 is within 1 standard deviation of the mean.
17
|17 - 20.4| = 3.4 < 7.9
17 is within 1 standard deviation of the mean.
19
|19 - 20.4| = 1.4 < 7.9
19 is within 1 standard deviation of the mean.
24
|24 - 20.4| = 3.6 < 7.9
24 is within 1 standard deviation of the mean.
25
|25 - 20.4| = 4.6 < 7.9
25 is within 1 standard deviation of the mean.
26
|26 - 20.4| = 5.6 < 7.9
26 is within 1 standard deviation of the mean.
28
|28 - 20.4| = 7.6 < 7.9
28 is within 1 standard deviation of the mean.
33
|33 - 20.4| = 12.6 > 7.9
33 is not within 1 standard deviation of the mean.

Answer:
The mean score for the students is 593.33.
Step-by-step explanation:
The table gives the scores of 6 students from a class of 25 in a competitive exam.
Name : Julia Andrew Jason Cathy Jessica Robert
Score : 650 550 380 720 710 550
Mean = Sum of the data values / Total number of data values
Mean = ( 650 + 550 + 380 + 720 + 710 + 550 ) ÷ 6
= 3560 ÷ 6 =593.33
The mean score for the students is 593.33.
