1. The resistances of ten randomly selected 100-ohm resistors have been recorded: 79.9, 85.9, 87.0, 96.7, 107.4, 100.8, 115.4, 117.9, 98.0, and 102.6. The individual resistances are known to follow a normal distribution with a mean of 100 ohms and a standard deviation of 10 ohms. (a) Calculate the sample mean resistance associated with the ten resistors. (b) For a sample size of ten, find the prob of obtaining a sample mean as large as or larger than the one calculated in part (a). ( c ) For a sample size of ten, find the probability of obtaining a sample mean with a resistance between 95 and 105 ohms.
