Assume the readings on thermometers are normally distributed with a mean of 0degreesc and a standard deviation of 1.00degreesc. find the probability that a randomly selected thermometer reads between negative 0.12 and 1.02

0.2983

Step-by-step explanation:

Let X be the reading on thermometer.  Given that X is N(0,1)

We are to find the probability that a randomly selected thermometer reads between negative 0.12 and 1.02

Reqd probability = .

Since this x is already normal std variable x=z

i.e. reqd prob =

Hence answer is 0.2983

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
