The data can be found in the Download csv file From this data, test the hypothesis that buying
flowers does not depend on the day of the week: (a) Formulate the appropriate statistical
hypotheses. 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. Observed Number of Thursdays = (c) if the null hypothesis is true, how many times
would you expect any weekday to occur? Expected Number = (Use one decimal) (d) Compute the
value of the test statistic Test Statistic = (use three decimals) (e) Find the P-value of your
hypothesis test. P-value = (use three decimals) (f) Using an of 0.08 , this data indicates the days
of the week that flowers are bought on is statistically to the customer's daim.(Part 2) A florist
claims that the number of people buying flowers on a Thursday is double that of any Monday,
Tuesday, or Wednesdoy (respectively) (i.e. pMenday = promey = pwedresieg =0.5 pThurtay ).
Additionally, they doim the number of people buying flowers on Fridays are similar to Thursdays
(i.o. Prhurndus = plridag) Let pMCinday= Prundoy = Piveliciday =a and let pThursiay=PFrFay=2a=
b then {a+a+a+b+b=12a=b They decide to use the same data in the file above to test the floriat 's
claim. (a) From this data, croate the null hypothesis that the forist is suggesting. H0:pMonday=
pTuesday =pWelnenday=pTuuridog=pFiday= (use five decimals) HA: At least one weekday
occurs disproportionately to what is atated in H0 (b) If her nuil hypothesis is true, how many times
would you expect any weekday to occur? Expected Number on Monday's= (Use one decimal)
24. Expected Number on Tuesday's= (Use one decimal) Expected Number on Wednesday's= (Use
one decimal) Expected Number on Thursday's= (Use one decimal) Expected Number on Fiday's
(Use one decimal) (c) Find the P-value probability expression of your hypothesis test P( DF: (d)
Using an of 0.08 , this data indicates the days of the week that flowers are bought on is statistically
