Yes, because 12 out of 15 want the street repaved, 12 divided by 15 equals 0.8 and that would be turned into a percent.

Answer:

0.8188 or 82%

0.0000643

Step-by-step explanation:

Given that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .0278 in.

If x is the dimension then X is N(0.0276, 0.0001)

Or $\frac{x-0.0276}{0.0001}$ is Normal (0,1)

a) Fraction of shelf depths are in specifications

= $P(0.0275$

b) For 98% to be within the specifications,

$\mu = 0.02765$

Margin of error = $0.0278-0.02775\\=0.00015$

For 98% critical value Z two tailed is 2.33

Hence std error = $\frac{0.00015}{2.33} \\=0.0000643$

So sigma should be = 0.0000643
