The next three questions are based on the following information: We're trying to determine if Lamborghini Aventador and Ferrari Enzo are different from each other based on their speed. In order to test this we record the average speed of 50 laps for each car. Which of the following is our alternate hypothesis O A. H1: Population average speed (Lamborghini) - Population average speed (Ferrari) = 0 O B. H1: Population average speed (Lamborghini) - Population average speed (Ferrari) not equal to 0 OC. H1: Population average speed (Lamborghini) - Population average speed (Ferrari) > 0 O D. H1: Population average speed (Lamborghini) - Population average speed (Ferrari) < 0

A population of scores with p = 38 and CT = 6 is standardized to create a new population with p = 50 and CT =10. What is the new value for each of the following scores from the original population? original score X = 26 X = 35 X = 44 X = 47
Read the following problem description then choose the correct null and alternative hypothesis. A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO is less than 1 in every one thousand.
Jerry is considering opening a new ice cream store at a certain location on State Street in Madison. Jerry conducts some analysis and determines that a given location is acceptable only if the number of pedestrians passing the potential location averages more than 100 per hour. To check if this location is acceptable, Jerry records the number of pedestrians observed for each of 40 hours. Jerry finds that the average number of pedestrians that pass the potential location during each of the 40 hours he was observing, is 105.7 per hour. Jerry assumes that he knows the population standard deviation to be 16. Can Jerry conclude at the 1% significance level that the potential location for the ice cream store is acceptable? a. What is the correct set of hypotheses? Answer: Ho: u = 100 and H1: u> 100 v b. Determine the p-value Answer: 0.0122 c. Interpret the results Answer: There is not enough evidence d. Jerry is concerned with committing a Type II error. Determine the probability of Type II…

need help for a practice test
A car company conducts crash tests of its new airbag system to evaluate its safety. One hundred cars are run into a solid concrete barrier at a speed of 35 miles per hour, and the chest compression of a crash test dummy is measured each time. They hope that the average compression if the test were repeated over and over (which we could think of as the population) would be about 2 inches, corresponding to an injury that would be painful but not fatal. In the hundred tests, the average chest compression in the crash test dummies was 2.1 inches, with an SD of 0.2 inches.(a) State the null and alternative hypotheses in terms of the problem.(b) What kind of box model will we use for this problem? A 0-1 box, or a box with other values on the tickets?(c) State the null and alternative hypotheses in terms of the box model (d) Compute the z test statistic and the p-value, using the sample average as your statistic as you compute z (e) What do you conclude?
Please answer question 4.1
The temperature of a certain chemical process is thought to be related to the time it takes for the process to reach completion. Out goal is to that relationship so that we can use it to predict TIME TO REACH COMPLETION at various TEMPERATURES. 14 trials are set up and the time for the process to complete is measured for each of the different temperatures. The data is presented here:(data is in the image added to the question as well as more questions to answer)
