In-s [12.5K]

Answer:

The correct answer is C.

Step-by-step explanation:

67^{th} percentile is represented as the value of probability in the norma distribution.

We look for a z-value with a left-tail of 0.67.

z=0.44

where,

z=\frac{x-M}{SD}

M: mean

SD: standar deviation

x=z×SD+M=0.44×0.3+M=M+0.132

The diameter of an orange at the 67^th percentile is 0.132 inch above the mean.
