The fracture strength of tempered glass averages 14.1 (measured in thousands of pounds per square inch) and has standard deviati
ololo11 [35]

Answer:

0.15866 is the probability of the average fracture strength of selected 100 pieces of glasses that of exceed 14.3.

Step-by-step explanation:

Given that, the strength of a tempered(x) a glass has average 14.1 and has standard deviation 2.

\mu_x=14.1 , \sigma_x=2

n=number of selected pieces= 100.

The probability that the average fracture strength of 100 pieces of this glass exceed 14.3 is

P(\overline X>14.3)=P(\frac{\overline X-\mu_x}{2/\sqrt n}>\frac{14.3-14.1}{2/\sqrt{100}})

                    =P(\overline X>1)

                    =1-P(\overline X\leq 1)

                    = 1 - 0.84134

                    =0.15866.
