. A group of students has been trained to increase their score on the math segment of the S.A.T.  For the general population, S.A.T.-Math scores are distributed N (505,105). It is reasonable to assume that the shape of the distribution is unchanged by training effects, but is shifted, hopefully to the right. It follows that we assume that σ=105. For a random sample, of size n = 100 the sample mean (Ms) S.A.T.-math score is 529. Compute a 99% confidence interval for µ, the mean score of the population of trained students.

The following data consists of WAT (word aptitude test) scores for a group of 25 young women students enrolled at a local college.   146.4 148.8 150.2 151.1 152.5 147.4 149.2 150.3 151.3 152.9 147.8 149.5 150.5 151.6 153.2 148.3 148.6 149.7 149.9 150.8 150.9 151.8 152.2 153.9 154.8                               Put the data in your calculator to answer the following question. Compute the sample mean (barX)  for this data?

Higher Order Function Write a function, whole_sum(), which takes in an integer, n. It returns another function which takes in an integer, k, and returns True if the digits of k sum to n and False otherwise. You may use the below guidelines or you may suggest your own solution. def whole_sum(n):    “””    >>> whole_sum(21)(777)    True    >>> whole_sum(142)(10010101010)    False    “””    def check(k):        ___________________        while _____________:            _________________________            _________________________            _________________________        return __________________    return _________________
