4. Here are the number of holiday gifts purchased by 25 families randomly interviewed at a local mall at the end of the holiday season:

22, 18, 22, 26, 19, 14, 23, 27, 2, 18, 28, 28, 11, 16, 34, 28, 13, 21, 32, 17, 6, 29, 23, 22, 19

Make

a frequency table and
a grouped frequency table with 7 intervals and an interval width of 5.

Draw out what this would look like as a histogram and
describe the shape of the distribution.

Please answer in details.

Assume a good deck is 25% of each suit. Deal 4 cards. Record the number of cards for each suit. Calculate the proportion or percentage of each suit. (You can just focus on one suit if you want, e.g., hearts; 1 heart out of 4 would be .25 or 25% hearts.) Did you get 25% cards of each suit? Why or why not? Basing your decision only on the sample (pretending you do not know what is in the deck),...
