A custodian wishes to compare two competing floor waxes to decide which one is best. He believes that the mean of WaxWin is less than the mean of WaxCo. In a random sample of 20 floors of WaxWin and 17 of WaxCo. WaxWin had a mean lifetime of 26.4 with a standard deviation of 8.6 and WaxCo had a mean lifetime of 27.2 with a standard deviation of 6.6. Perform a hypothesis test using a significance level of 0.05 to help him decide. Let WaxWin be sample 1 and WaxCo be sample 2 The correct hypotheses are: Ο Ηο: μι < με HA: 1 > ₂ (claim) Ο Ho: με 2 με HA: 1₂(claim) O Ho: ₁ = ₂ HA: 12(claim) Since the level of significance is 0.05 the critical value is -1.69 (round to 3 places) The test statistic is: The p-value is: (round to 3 places)

Question
![A custodian wishes to compare two competing floor waxes to decide which one is best. He believes that the
mean of WaxWin is less than the mean of WaxCo.
In a random sample of 20 floors of WaxWin and 17 of WaxCo. WaxWin had a mean lifetime of 26.4 with a
standard deviation of 8.6 and WaxCo had a mean lifetime of 27.2 with a standard deviation of 6.6. Perform
a hypothesis test using a significance level of 0.05 to help him decide.
Let WaxWin be sample 1 and WaxCo be sample 2
The correct hypotheses are:
Ο Ηο: μι < με
HA₁₂(claim)
Ο Ηρ: με 2 με
HA: 1₂(claim)
O Ho: ₁ = ₂
HAM12(claim)
Since the level of significance is 0.05 the critical value is -1.69
(round to 3 places)
The test statistic is:
The p-value is:
