Question

Find the area of the shaded region. The graph depicts the standard normal distribution of bone density scores with mean 0 and standard deviation 1. The area of the shaded region is Find the indicated z score. The graph depicts the standard normal distribution with mean 0 and standard deviation 1. Assume that thermometer readings are normally distributed with a mean of 0 degree C and a standard deviation of 1.00 degree C. A thermometer is randomly selected and tested. For the case below, draw a sketch, and rind the probability of the reading. (The given values are in Celsius degrees) Between -1.38 and 1.56 The probability of getting a reading between - 1.38 degree C and 1.56 degree C is

Explanation / Answer

Area of the shaded region = P( Z> -1.09) = 0.8621

The indicated Z score corresponding to a left tail probability of 0.1660 is -0.97

The correct sketch of P (-1.38<X<1.56) is option (C)

The probability of getting a reading between the mentioned values is 0.8568
