A portion of the monthly stock prices (rounded to the nearest dollar) for Starbucks Corp. and Dunkin' Brands Group, Inc. from 2017 to 2019 are reported in the following table.

a.State the null and the alternative hypotheses in order to determine if the variance of price differs for the two firms, where the populations 1 and 2 refer to Starbucks and Dunkin', respectively.

multiple choice 1

• H₀:₁²/₂²= 1,H_A:₁²/₂² 1
• H₀:₁²/₂² 1,H_A:₁²/₂²> 1
• H₀:₁²/₂² 1,H_A:₁²/₂²< 1

b.Calculate the value of the test statistic.(Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)

Test Statistic =

c.Find thep-value.

multiple choice 2

• p-value < 0.01
• 0.01 p-value < 0.025
• 0.025 p-value < 0.05
• 0.05 p-value < 0.10
• p-value 0.10

d.At= 0.05 what is your conclusion?

multiple choice 3

• RejectH₀; we can say that the variance of prices differs for the two firms.
• RejectH₀; we cannot say that the variance of prices differs for the two firms.
• Do not rejectH₀; we can say that the variance of prices differs for the two firms.
• Do not rejectH₀; we cannot say the variance of prices differs for the two firms.
