2.5 In the interest of laziness, I’m going to place all three time series in a single graph. What do I conclude from these series? That the three trends were very similar. 0 50 100 150 200 1970 1975 1980 1985 1990 Year Total Service Physician Fees Hospital Room Charges 2.8a. A moderate number of classes ( for a moderately sized dataset ) . 2.14a. The stem - and - leaf diagram: 1* | 68 2* | 1255578899 3* | 1145566677778999 4* | 000122345678999 5* | 11667 6* | 12 2.16. Since all the numbers have six in the hundredths place, I would separate the stem and leaf between the tens and ones places. 64* | 68 65* | 02233458 66* | 2679

67* | 011478899 68* | 2 2.17. The only notable thing is that I would treat these all as four - digit numbers ( zero is the first digit of the numbers less than 1000 ) , and I would divide the stem and leaf between the thousands and hundreds places. 0*** | 192,453,558,558,621,662,669,743,809,857,911,913,924,998 1*** | 015,079,092,097,106,138,160,187,210,213,225,300,400,431,457, . .. 2*** | 114,135,266,331,540,657,706
