A savings and loan association needs information concerning the checking account balances of its local customers. a random sample of 14 accounts was checked and yielded a mean balance of $664.14 a nd a standard deviation of $297.29. use this data to find a 98% confidence interval for the true mean checking account balance for all local customers.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

the infinity sign
