A researcher carried out an investigation of the extra sleep produced by drug A and drug B. The data from the experiment in hours are shown. Drug A 0.7 −1.6 −0.2 −1.2 −0.1 3.4 3.7 0.8 0.0 2.0 Drug B 1.9 0.8 1.1 0.1 −0.1 4.4 5.5 1.6 4.6 3.4 The data for both treatment groups are not normally distributed. To determine if the mean sleep response (extra hours of sleep produced) differs between drug A and drug B, a permutation test was performed. This was done by pooling both groups of data and randomly reassigning half the observations to the drug A group, and the other half to the drug B group. The difference of means for these two groups, ?⎯⎯⎯⎯?−?⎯⎯⎯⎯? , was then calculated and recorded. This permutation process was repeated a large number of times. The histogram shows the resulting distribution of values for the mean difference for all the permutations. Nearly symmetric histogram centered at 0 with vertical dashed lines at -1.8 and +1.8, separating the critical region from the non-critical region With a null hypothesis of no difference in the amount of extra sleep between the two drugs, and a two‑sided alternative hypothesis, determine if the actual observed difference is statistically significant. The dashed lines represent the critical values at −1.8 and 1.8, and the total area in the tails of the histogram is 0.05 , which represents the critical (rejection) region.

Compute the difference of the means of the two drugs for the observed data. Give your answer to two decimal places.

1. Collect Mileage information:

   Prompt: "Starting Odometer Reading:\n"

   Variable: odoStart = ?

   Prompt: "Ending Odometer Reading:\n"

   Variable: odoEnd = ?

   Add code to PRINT odoStart and odoEnd variables as well as the totalMiles to check your work.

   The following data will be used as input in the test:

   odoStart = 1234
   odoEnd = 2222
