Len [333]

Answer:

Standard deviation of the length of granola bars produced at Bernie's Bars is 0.50      

Step-by-step explanation:

We are given the following information in the question:

Formula:

z_{score} = \displaystyle\frac{x - \mu}{\sigma}

where,

μ is the mean and σ is the standard deviation.

Putting the values we get:

\displaystyle\frac{ 3- \mu}{\sigma} = 1\\\\3 = \sigma + \mu\\\\\displaystyle\frac{ 3.5- \mu}{\sigma} = 2\\\\3.5 = 2\sigma + \mu

Solving the two obtained equations:

Subtracting the two obtained equation, we have:

3.5-3 = \mu + 2\sigma - \mu -\sigma\\\sigma = 0.5

Hence,  standard deviation of the length of granola bars produced at Bernie's Bars is 0.50
