In the road test he wishes to use cars as blocks; however, because of a timeconstraint, he must use an incomplete block design. He runs the balanced design with thefive blocks that follow. Analyze the data from this experiment (use a = 0.05) based on the SSfor additives adjusted for cars and draw conclusions.CarAdditive123411714131221414131031213129413111112111210

Suppose a sample of 16 light trucks is randomly selected off the assembly line. The trucks are driven 1000 miles and the fuel mileage (MPG) of each truck is recorded. It is found that the mean MPG is 22 with a SD equal to 3. The previous model of the light truck got 20 MPG. Conduct a one-sample t-test using the seven-step process and with this information, what can you conclude in step 6? Group of answer choices a. Fail to reject H0 b. Not enough information to make a decision c. Reject H0 d. The one-sample t-test is not the correct test
2. Differentiate Independent and Dependent Samples and give an example for each method.
A student decides to spin a dime and determine the proportion of times it lands on heads. The student spins the dime 25 times and records that it lands on heads 17 times. Let p = the true proportion of times the dime would land on heads when spun. Under the assumption that the true proportion is 0.5, 100 simulated proportions for samples of size 25 are shown in the dotplot. Using the dotplot, what do the two dots above 0.70 represent? There is a 2 in 100 chance that the true proportion of heads is 0.7. In two simulated samples of 25 spins, the proportion of heads is 0.7. There is a 2 in 100 chance that the sample proportion of heads is 0.7. In two simulated samples of 25 spins, the true proportion of heads is 0.7.
A paper investigated the driving behavior of teenagers by observing their vehicles as they left a high school parking lot and then again at a site approximately mile from the school. Assume that it is reasonable to regard the teen drivers in this 2 study as representative of the population of teen drivers. Amount by Which Speed Limit Was Exceeded Female Driver -0.1 0.4 1.1 0.7 1.1 1.2 0.1 0.9 0.5 0.5 (a) Use a .01 level of significance for any hypothesis tests. Data consistent with summary quantities appearing in the paper are given in the table. The measurements represent the difference between the observed vehicle speed and the posted speed limit (in miles per hour) for a sample of male teenage drivers and a sample of female teenage drivers. (Use males-females. Round your test statistic to two decimal places. Round your degrees of freedom down to the nearest whole number. Round your p-value to three decimal places.) t = df = P= Male Driver 1.4 1.2 0.9 2.1 0.7 1.3 3 1.3 0.6 2.1 (b) Do…

Clothes dried outside smell better than those dried in a dryer because of a process called photolysis. Sunlight breaks down compounds that cause odor. A trained smeller is asked to smell a random sample of 20 towels. The smeller does not know it, but all of the 20 towels have been dried in the sun. The smeller is blindfolded and is not allowed to touch the towels but leans forward to smell the towel then rates the towel on a smell-scale of 1 to 10, where 1 is the an extremely unpleasant smell and 10 is a very good smell. A smell rating of 8 is typically attributed to a towel that is dried in the dryer. The mean smell rating for these 20 towels is approximately normal with a mean of 8.45 and the standard deviation is 0.887. A statistician performs a test of Ho: μ = 8 versus H₁ μ> 8 where is the true mean smell rating for all towels dried in the sun. This test yields a P-value of 0.0176. What conclusion would you make at the significance level a = 0.01? Because the P-value of 0.0176 > a…

In an early Gregor Mendel’s study, he crossed two hybrid pea plants and recorded theform (round or wrinkled) and albumen color (yellow or green) of the fertilized seed. Hetheorized that these should appear in the following proportionsRound, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green9/16 3/16 3/16 1/16The observed counts were as follows:Round, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green Total315 101 108 32 5560. What are the expected counts?Round, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green Total556Test to see if the observed counts confirm Mendel’s theory. Use ? = 0.05.1.
