Multi part question needing assistance please.

1. Assume that the readings at freezing on a batch ofthermometers are normally distributed with a mean of 0°C and astandard deviation of 1.00°C. A single thermometer is randomlyselected and tested. Find the probability of obtaining a readinggreater than -1.378°C. P(Z>−1.378) _____________ ******* WHAT DOI DO ABOUT THE 8? I CAN SEE ON THE CHART THE -1.37 BUT DONT KNOWWHAT TO DO CONCERNING THE 8.

2. Assume that the readings at freezing on a batch ofthermometers are normally distributed with a mean of 0°C and astandard deviation of 1.00°C. A single thermometer is randomlyselected and tested. Find the probability of obtaining a readingbetween 1.141°C and 2.549°C. P(1.141

3. About % of the area under the curve of the standard normaldistribution is between z=−2.159 and z=2.159 (or within 2.159standard deviations of the mean).
