Is this homework? Sounds like it.
Basically use csvread() or importdata() to read in the data. Then look at columns 4 - 9 and see which are 9 or less. Untested code:
lessThan9 = data(:, 4:9) <= 9; % Logical array of what values are less than 9.
% Find out which rows have at least 5 less than 9
sums = sum(lessThan9, 2);
goodRows = sums >= 5;
% Get the dates in the separate arrays for month, day, and year
% (same format that it gave the data to us in).
goodMonths = data(goodRows, 1);
goodDays = data(goodRows, 2);
goodYears = data(goodRows, 3);
theSums = sums(goodRows)
% For fun, print them out.
for k = 1 : length(goodMonths)
fprintf('%d - %d - %d had % numbers less than or equal to 9.\n'...
goodMonths(k), goodDays(k), goodYears(k), theSums(k))
end
