Assume that thermometer readings are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degrees C.

Cerrena [4.2K]

Answer:

The probability of getting a reading between -1.42 degree C and 1.61 degree C is 0.8685.

Step-by-step explanation:

We are given that

$Mean,\mu=0$ degree C

Standard deviation, $\sigma=1$ degree C

We have to find the probability of the reading between -1.42 and 1.61.

$P(-1.42$

Using the formula

$P(a$

$P(-1.42$

Hence, the probability of getting a reading between -1.42 degree C and 1.61 degree C is 0.8685.
