Is it reasonable to conclude there is no preference among these four items?

Test at 0.05 significance level.

Item	Observed Selection	Expected Selection
A	32	30
B	24	30
C	35	30
D	29	30

Step 1. State Hypothesis

Ho: There is no difference in proportion of selection of each item

Ha: There is a difference in proportion of selection of each item

Step 2. Select the Level of Significance

In this case = 0.05

Step 3. Select Test Statistic

Select Chi-square

Step 4. State the Decision Rule

If the Chi-square p value is greater than the critical value then Ho should be rejected

Step 5. Calculate Critical Value

CHISQ.INV.RT (probability, deg.freedom)

= CHISQ.INV.RT(0.05,3) =

Step 6. Calculate Chi-square p value

Returns p-value

Step 7. Apply the decision rule to draw your conclusions.
