If power is "the probability of detecting a real effect if a real effect exists in nature" explain what its mutually exclusive alternative is. (Hint: What is a more common name for the probability of not-detecting a real effect if a real effect exists in nature?)

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
