Prior to a recent gubernatorial election, a survey was conducted to determine whether there was a relationship between sexual gender and preference for the Democratic or Republican candidate. The following data were recorded. Assume the data will be analyzed with Chi-square.                                        Candidate e Preference                                          Republican   Democrat            Female                        82                  118          200               Male                         68                   132          200                                               160                   250         400     The value of χ2obt = _________.

2.) Explain why the relative frequency column of a frequency table might not sum to 1.0.

The following data are the maximum temperatures (in degrees Fahrenheit) of 17 cities in the United states measured on the same day. 53 70 65 74 85 76 84 70 61 59 54 66 56 71 81 73 76 Construct a box and whisker plot for the data.

Answer for b c d

Listed below are pulse rates (beats per minute) from samples of adult males and females. Does there appear to be a difference? Find the coefficient of variation for each of the two samples, then compare the variation. Male 89 70 60 69 68 51 66 55 81 70 60 64 98 54 65 D Female 66 83 80 71 72 86 87 88 90 89 92 72 86 78 79 The coefficient of variation for the male pulse rates is % (Type an integer or decimal rounded to one decimal place as needed.) The coefficient of variation for the female pulse rates is % (Type an integer or decimal rounded to one decimal place as needed.). Compare the variation. The coefficients of variation for each data set are EX Therefore, the male pulse rates vary the female pulse rates.
