Step-by-step explanation
Ok for me to tell you I'm going to give an example.
Data set=
40,50,60,30,105,19,40
For this data set our mode would be 40 because mode is the number that appears most in a data set and as you can see 40 appears twice while every other number only appears once.
For median=would also be 40.
Because median is the number that is in the middle when you sort them least to greatest so 40 is in the middle when you put them in least to greatest.
The maximum is 105
Because the maximum is the highest number in the data set so 105 is the biggest number.
Range is 86.
For range is the highest number subtracting the lowest number and highest number is 105 and lowest number is 19 so 105 - 19=86
Hope this helps have a great day:)
Quotient means division.. 23/u-t or written out is 23 divided by U minus T

Empirical rule dictates that, in a Bell-shaped distribution, 95% of data lies within 2 standard deviation on either side of the mean.
Therefore,
Lower value = mean-2SD = 70-2*8 = 70-16 = 54
Upper value = mean+2SD = 70+2*8 = 70+16 = 86
Then, 95% of the data lies between $54 and 84. These values can also be taken as the true mean of the population considering 95% confidence when sample mean has been calculated. In this regard, 2SD can be regarded as the margin error.
The answer to the question is b
