Assume that the readings on scietific thermometers are normally distributed with a mean of 0 0C and a standard deviation of 1 0C
lys-0071 [83]

Answer:  0.8531

Step-by-step explanation:

Let x be the random variable that represents the readings on scientific thermometers .

Given : The readings on scientific thermometers are normally distributed,

Population mean : \mu=0^{\circ}\ C

Standard deviation : \sigma=1^{\circ}\ C

Z-score : z=\dfrac{x-\mu}{\sigma}

Now, the z-value corresponding to -1.05 :  z=\dfrac{-1.05.-0}{1}=-1.05

P-value = P(x>-1.05)=P(z>-1.05)=1-P(z\leq-1.05)

=1-0.1468591=0.8531409\approx0.8531\text{ (Rounded to four decimal places)}

Hence, the probability of the reading greater than -1.05 in degrees Celsius.= 0.8531
