At burnt mesa pueblo, archaeological studies have used the method of tree-ring dating in an effort to determine when prehistoric people lived in the pueblo. wood from several excavations gave a mean of (year) 1234 with a standard deviation of 31 years. the distribution of dates was more or less mound-shaped and symmetric about the mean. use the empirical rule to estimate the following. (a) a range of years centered about the mean in which about 68% of the data (tree-ring dates) will be found between and a. d. (b) a range of years centered about the mean in which about 95% of the data (tree-ring dates) will be found between and a. d. (c) a range of years centered about the mean in which almost all the data (tree-ring dates) will be found between and a. d.

step-by-step explanation:

50

step-by-step explanation:

$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
