Some people believe that different octane gasoline result in different miles per gallon in a vehicle. The following data is a sample of 11 people which were asked to drive their car only using 10 gallons of gas and record their mileage for each 87 Octane and 92 Octane. Miles with 87 Octane Miles with 92 Octane Person 1. 234 237 257 238 3 243 229 4 215 224 114 119 6 287 297 315 351 8 229 241 9 192 186 10 204 209 11 547 562 Do the data support that different octanes produce different miles per gallon at the a = 0.02 level of significance? Note: A normal probability plot of difference in car mileage between Octane 87 and Octane 92 indicates the population could be normal and a boxplot indicated no outliers. a. Express the null and alternative hypotheses in symbolic form for this claim. Assume 4 = 4i – P2, where µi is the population mean mileage for Octane 87 and u2 is the mean mileage for Octane 92. Ho: 4, Select an answer V H1:µ, Select an answer V b. What is the significance level? c.…
3. The following data are the joint temperatures of the O-rings (°F) for each test firing or actual launch of the space shuttle rocket motor (from Presidential Commission on the Space Shuttle Challenger Accident, Vol. 1, pp. 129–131): 84, 44, 41, 53, 57, 61, 65, 52, 58, 57, 50, 62, 60, 68, 62, 69, 68, 68, 71, 70, 72, 68, 73, 71, 70, 74, 75, 73, 79, 81, 76, 77, 77, 83, 31, 83. Compute the sample mean, sample standard deviation, and sample median using the formula introduced in the lecture. Hint: you can use Excel function to verify the results but must apply the formula in lecture to solve the problem.
The following test scores are for two classes that took the same test. (The highest possible score on the test was 60.) Class 1 (24 scores): 37, 46, 54, 55, 15, 55, 44, 55, 37, 26, 52, 44, 31, 23, 44, 52, 41, 41, 30, 50, 41, 41, 41, 41 Class 2 (25 scores): 50, 40, 40, 25, 40, 57, 31, 31, 40, 31, 33, 33, 57, 33, 34, 34, 57, 29, 34, 41, 41, 58, 41, 34, 45 Form a back-to-back stem and leaf plot with one stem. Put the leaves for one class on the right side of the stem and the leaves for the other class on the left side. Record the leaves in increasing order from the stem.

The ability of lizards to recognize their predators via tongue flicks can often mean life or death for lizards. Seventeen juvenile common lizards were exposed to the chemical cues of the viper snake. Their responses, in number of tongue flicks per 20 minutes, are presented below. 319, 676, 710, 455, 744, 200, 370, 200, 472, 336, 455, 642, 795, 795, 438, 540, 489 Assuming normal distribution, a) Find a 90% confidence interval for the mean number of tongue flicks per 20 minutes for all juvenile common lizards. Assume a population standard deviation of 190.0. Note: The sum of the data is 8636. Confidence interval: (, ). b) Which of the following is the correct interpretation for your answer in part (a)? A. We can be 90% confident that the mean number of tongue flicks per 20 minutes for this sample of 17 lizards lies in the interval B. There is a 90% chance that the mean number of tongue flicks per 20 minutes for all juvenile common lizards lies in the interval C. We can be 90% confident…
