Construct a frequency polygon for the following:

(a) $$\begin{array}{cc}\text{Pulse rates for Females}& \text{Frequency}\\ \text{60–69}& \text{12}\\ \text{70–79}& \text{14}\\ \text{80–89}& \text{11}\\ \text{90–99}& \text{1}\\ \text{100–109}& \text{1}\\ \text{110–119}& \text{0}\\ \text{120–129}& \text{1}\end{array}$$
(b) $$\begin{array}{cc}\text{Actual speed in a 30 MPH zone}& \text{Frequency}\\ \text{42–45}& \text{25}\\ \text{46–49}& \text{14}\\ \text{50–53}& \text{7}\\ \text{54–57}& \text{3}\\ \text{58–61}& \text{1}\end{array}$$
(c) $$\begin{array}{cc}\text{Tar (mg) in nonfiltered cigarettes}& \text{Frequency}\\ \text{10–13}& \text{1}\\ \text{14–17}& \text{0}\\ \text{18–21}& \text{15}\\ \text{22–25}& \text{7}\\ \text{26–29}& \text{2}\end{array}$$
