From this data, test the hypothesis that buying flowers does not depend on the day of the week.
(a) Formulate the appropriate statistical hypotheses.
A. Ho : PMonday = Pruesday = Pwednesday = Prhursday

= 0.20
HA: PMonday + Pruesday + Pwednesday # Prhursday # Priday
В. Но : РМопday — Ртиesdaу — Рwednesday
= PThursday = P Friday
0.20
HA: At least one weekday occurs disproportionately
С. Но : Рмоnday
= PTuesday
= Pwednesday = Prhursday = PFriday
На : РМоnday 7 PТuesday
+ Pwednesday
+ PThursday + PFriday
D. Ho : PMonday = PTuesday = Pwednesday
PThursday = PFriday = 0.20
HA: At least one weekday occurs disproportionately
Е. Но : РМоnday —
PTuesday = PwWednesday = PThursday =
= PFriday
= 0.20
HA: PMonday # PTuesday + Pwednesday + PThursday + PFriday
Recall to run a goodness of fit test the following assumptions must hold: 'Sample was selected without bias','Data is categorical','Sample size is less than 10% of population size', and the 'Expected values are all 5 or greater'
(b) Find the number of times each day of the week was observed.
