Answer:

0.42 & 0.55

Step-by-step explanation:

Mean length = 0.42 + 0.53+ 0.55 + 0.48 + 0.51/5

= 0.498

0.42 - 0.498 = - 0.078‬

0.53 - 0.498 = 0.032‬

0.55 - 0.498 = 0.052‬

0.48 - 0.498 = - 0.018‬

0.51 - 0.498 = 0.012‬

The nails to be thrown out are:

0.42 & 0.55 because their deviations from the mean are not within 0.05 inch
