The temperature recorded by a certain thermometer when placed in boiling water (true temperature 100 degree C) is normally distributed with mean p=99.8 degree C and standard deviation sigma =1-1 degree C. a) What is the probability that the thermometer reading is greater than 100 degree C? b) What is the probability that the thermometer reading is within +- 0.05 degree C of the true temperature? c) What is the probability that a random sample of 30 thermometers has a mean thermometer reading is less than 100 degree C? (inclusive)

a) The probability that the thermometer reading is greater than 100 degree C is approximately 0.1587.

b) The probability that the thermometer reading is within +- 0.05 degree C of the true temperature is approximately 0.3830.

c) The probability that a random sample of 30 thermometers has a mean thermometer reading less than 100 degree C is approximately 0.0001.

a) Using the Z-score formula, we get Z = (100 - 99.8)/1.1 = 0.182. Looking up the standard normal distribution table, we find the probability of a Z-score being greater than 0.182 is 0.1587.

b) To find the probability that the thermometer reading is within +- 0.05 degree C of the true temperature, we need to find the area under the normal distribution curve between 99.95 and 100.05.

Using the Z-score formula for the lower and upper limits, we get Z1 = (99.95 - 99.8)/1.1 = 0.136 and Z2 = (100.05 - 99.8)/1.1 = 0.364. Looking up the standard normal distribution table for the area between Z1 and Z2, we find the probability is 0.3830.

c) The sample mean follows a normal distribution with mean 99.8 and standard deviation 1.1/sqrt(30) = 0.201. Using the Z-score formula, we get Z = (100 - 99.8)/(0.201) = 0.995. Looking up the standard normal distribution table for the area to the left of Z, we find the probability is approximately 0.0001.
