True or False the probability that a standard normal random variable Z is between 1.50 and 2.10 is the same as the probability Z is between -2.10 and -1.50.?

True or false only a variable can be a factor?
False.
The variable not related to the purpose of th study but may affect the dependent variable are termed as extraneous variable true or false?
False: they are called exogenous.
