Assume that the reading on the thermometers are normally distributed with a mean of 0 and standard deviation of 1.00 C. A thermometer is randomly selected and tested draw a sketch and find the temp reading corresponding to

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
