The required solutions to the questions are explained below:

1. For Car wash

  • Relative frequency for Juniors = [tex]\frac{37}{66}[/tex] x 100%

                                                   = 56.06

Relative frequency for Juniors = 56.1%

  • Relative frequency for Seniors = [tex]\frac{29}{66}[/tex] x 100%

                                                      = 43.94

Relative frequency for Seniors = 43.9%

  • Total in percentage = 56.1% + 43.9%

                                            = 100%

2. For Bake sale

  • Relative frequency for Juniors = [tex]\frac{25}{44}[/tex] x 100%

                                                         = 56.82

Relative frequency for Juniors = 56.8%

  • Relative frequency for Seniors = [tex]\frac{19}{44}[/tex] x 100%

                                                           = 43.18

Relative frequency for Seniors = 43.2%

  • Total in percentage = 56.8% + 43.2%

                                            = 100%

3. For Talent show

  • Relative frequency for Juniors = [tex]\frac{16}{44}[/tex] x 100%

                                                            = 36.36

Relative frequency for Juniors = 36.4%

  • Relative frequency for Seniors = [tex]\frac{28}{44}[/tex] x 100%

                                                           = 63.64

Relative frequency for Seniors = 63.6%

  • Total in percentage = 36.4% + 63.6%

                                          = 100%
