All results and explanations need to be reported Within this Word document after each question. Your results should be formatted and edited. Make sure to use complete sentences when explaining your results. You need to submit a hard copy of your lab. Exercise 1. A research firm claims that the distribution of the days of the week that people are most likely to order food for delivery is different from the distribution shown in the pie chart. You randomly select 496 people and record which day of the week each is most likely to order food for delivery. The table to the right shows the results. At a = .10 test the research firm's claim. Food at your door Day Frequency_f Sunday 7% Sunday 44 Monday 3% Tuesday 6% Monday 14 Wednesday 12% Tuesday 29 Thursday 9% Wednesday 41 Friday 35% Thursday 46 Saturday 28% Friday 166 Saturday 156Exercise 2. A beer industry association conducts a survey to determine the preference of beer drinkers for light, regular, and dark beers. A sample of 200 beer drinkers is taken with each person in the sample asked to indicate a preference for one of the three types of beers: light, regular, or dark. At the end of the survey questionnaire, the respondent is asked to provide information on a variety of demographics including gender: male or female. A research question of interest is whether preference for the three types of beer is independent of the gender of the beer drinker. If beer drinkers' preferences depend on their gender, then beer manufacturers could use this information to customize its promotions and advertising for the different target markets of beer drinkers. A. Construct a two-way contingency table (crosstabulation) with beer preferences (light, regular and dark) and gender (male and female) to summarize the data. B. Use the contingency table (crosstabulation) constructed in Part A, construct a bar graph that shows the relationship between beer preferences and gender. Discuss whether there is dependence exists between beer preferences and gender. C. Construct another two-way contingency table (crosstabulation) and find the expected frequency for each cell. D. Check whether each expected frequency is at least 5. E. State Ho and Ha. F. At the 5% significance level, perform a hypothesis test to determine whether beer drinkers' preferences depend on their gender
