Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and a standard deviation of 1 degrees C. A thermometer is randomly selected and tested. Find the probability of a reading that is less than -2.75.

Solution Summary

This solution finds the probability that a thermometer reading is less than -2.75 in a normal distribution of thermometer readings.

If the reading of the thermometer is normally distributed with a mean 0.0 C and a standard distribution of 1.0 C, find the probability that a reading is:
a. Between 0.0 and (0.04)n C
b. Less than (-0.04n) C

Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and a standard deviation of 1 degrees C. A thermometer is randomly selected and tested. Find the probability of a reading that is between 2.00 and 2.34

Assume that the readings on the thermometers are normally distributed with a mean of zero degrees and a standard deviation of 1 C. A thermometer is randomly selected and tested. Find the probability of a reading that is between -3.88 and 1.07.

If 0.5% of the thermometers are rejected because they have readings that are too low and another 0.5% are rejected because they have readings that are too high, find the two readings that are cutoff values separating the rejected thermometers from the others.

Dear OTA,
Please help me in solving the following problems.
=======================
Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and a standard deviation of 1.00 degree C. A thermometer is randomly selected and tested. In each case, draw a sketch and find the probability

1. Assume that a class length between 50.0 min and 52.0 min is randomly selected, and find the probability that the given time is seletced.
Between 50.5 min and 51.8 min
2. Assume that voltages in a circuit vary between 6 volts and 12 volts, and voltages are spread evenly over the range of possibilities, so that there is a

Assume the readings on the thermometers are normally distributed with a mean of 0 degress and a standard deviation of 1.00 degree. Find the indicated probability, where z is the reading in degrees.
P(z > -2.575)
I need to show the work and formula used.
Thank you.

A thermometer is removed from a room where the temperature 70 degrees F and is taken outside, where the temperature is 10 degrees F. After one-half minute the thermometer reads 50 degrees F. What is the reading of the thermometer at t=1 minute? How long will it take for the thermometer to reach 15 degrees F?

Assume that women's height are normally distributed with a mean given by =63.4 in, and a standard deviation given by =2.7in.
If 1 woman is randomly selected, find the probability that her height is less than 64 in.
If 46 women are randomly selected find the probability that they have a mean height les
