Question

A. For a standard normal distribution, find:

P(-1.14 < z < -0.41)

B. For a standard normal distribution, given:

P(z < c) = 0.0278

Find c.

C. For a standard normal distribution, find:

P(z > c) = 0.4907

Find c.

D. Assume that z-scores are normally distributed with a mean of 0 and a standard deviation of 1. IfP(0<z<a)=0.4686P(0<z<a) = 0.4686

find a.

E. Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading between -1.573°C and 2.901°C.

P(-1.573<Z<2.901)=
