Parameter is a function of population values. Here the parameter
is population proportion 
, since we had to test whether the total proportion of adults in
us have greater confidence in banks and other financial
institutions is less than 0.15(15%).
Now statistic is a function of sample values. Here a random sample of size 1325 is chosen and out of these a proportion of 0.111(111%) said they they have greater confidence in the same. Therefore sample proportion is the statistic here.
