Question

is there a way to find answer by plugging this into calculator? thanks!

A marketing research firm wishes to study the relationship between wine consumption and whether a person likes to watch professional tennis on television. One hundred randomly selected people are asked whether they drink wine a whether they watch tennis. The following results are obtained: Drink Wine Do Not Drink Wine Totals Do Not Tennis Watch Tennis Totals 48 32 80 57 20 100 (a) For each row and column total, calculate the corresponding row or column percentage Row 1 Row 2 Column 1 Column 2 (b) For each cell, calculate the corresponding cell, row, and column percentages. (Round your answers to the nearest whole number.) Do Not Watch Tennis Drink Wine Cell- Cell- Do Not Drink Wine Cell- Cell % Column. (c) Test the hypothesis that whether people drink wine is independent of whether people watch tennis. Set ?-.05. (Round your answer to 3 decimal places.) | (Click to select) ? HO. conclude that whether a person drinks wine and whether a person watches tennis are 1 (Click to se ect)2 events.

Explanation / Answer

This is definitely be answered with a simple calculator. There is not much involved in the first two questions. But you certainly need Chi-square table to answer the third question.

a) Row 1 = Drink wine/Total = 57/100 =0.57

Row 2 = Do not drink wine/ total = 43/100 = 0.43

Column 1 = watch tennis / total = 20/100 = 0.2

column2 = don not watch / total = 80/100 = 0.8

b)drink wine cell and watch tennis = 9/100 = 0.09

row = 9/57

column = 9/20

drink wine cell and do not watch tennis

cell = 48/100

row = 48/57

column = 48/80

do not drink wine cell and watch tennis

cell = 11/100

row = 11/43

column = 11/20

do not drink wine cell and do not watch tennis

cell = 32/100

row = 32/43

column = 32/80

c) Chi square can be found from chi square table with alpha = 0.06
