Answer:
The length of the brown shelf is 11ft
Step-by-step explanation:
In this question, we are asked to calculate the length of a brown shelf, given that the length of the orange shelf is a particular length.
Now as we are told from the question, the length of the brown shelf is twice that of the yellow shelf. What we simply need to do is to multiply the length of the orange shelf by 2 to get the length of the brown shelf.
The length of the orange shelf is 5ft 6 inches, multiplying this by 2 will yield a length of 10ft 12 inches
Now, since 1ft = 12 inches, this means the length of the brown shelf would be 11ft in total

Step-by-step explanation:
it sucks
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.
