A single thermometer is randomly selected and tested. Find the probability of obtaining a reading between -1.821°C and -1.156°C. Round your answer to 4 decimal places P(-1.821

Explanation / Answer

Sol:

P(-1.821<Z<-1.156)

=P(Z<-1.156)-P(Z<-1.821)

Rocde to use pnorm function:

pnorm(-1.156,mean=0,sd=1)-pnorm(-1.821,mean=0,sd=1)

=0.08953715

=0.0895

ANSWER:0.0895
