22.75x + 13.50 = 150
Step-by-step explanation:
Ответ:
0.24
Explanation:
To find the population mean, add together all of the values in the population:
0+2+3+2+1+3+2+3+4+3+3+2+3+2+5+1+5+2+3+2+3+4+1+3+4 = 66
Now divide by the number of data points, 25:
66/25 = 2.64
To find the sample mean, add together all of the values in the sample:
0+2+3+3+4 = 12
Divide by the number of data points, 5:
12/5 = 2.4
The difference is 2.64-2.4 = 0.24
