What is the “Big-Oh” time complexity of the following method?     public static void foo(int n, int sum) {        int i = n;        while (i > 1) {            for (int j = 0; j < n * n; j++) {                sum++;            }            i = i / 2;        }    }

A study found that the mean systolic blood pressure was 106 mm Hg. Assume that the systolic blood pressure follows a normal distribution with mean = 106 mm Hg and a standard deviation of 8 mm Hg. What is the probability that a randomly selected systolic blood pressure is greater than 100 mm Hg?  Round your answer to two decimal places.
