Customers with these vehicles are suffering substantialdamage and repair costs in low-speed impacts to the bumpers. The company has been solicitingproposals for a new collapsible bumper system to upgrade the performance of their sedans to beequal to the industry average of $400 or less in a collision impact of ≤15 miles per hour (mph).Gruman Engineers believe they have found a bumper system that will meet this requirement. Todemonstrate it, they crashed six sedans with this bumper into a barrier at 15 mph, submitted themfor repairs and recorded the cost of the repairs. The mean and standard deviation of the costs arefound to be $458 and $48, respectively. At the α = .05 significance level, does the test datacontradict the manufacturer’s claim that the repair cost does not exceed $400? a)What is known?

Assuming the goal is tominimize the expected cost due to fuel cell shortages, set upa dynamic programming model that could be used todetermine how to stock the space shuttle with fuel cells.There are T different types of fuel cells.
- A medical researcher says that less than 79% of adults in a certain country think that healthy children should be required to be vaccinated.

Use SAS to complete each problem below. (a) It is believed that about 4% of controls live close to the plant and the OR that investigators would be interested in detecting is 3.5. Assuming that a 2-sided, 5% level test will be conducted, what power will the test have for detecting a significant association between cancer and proximity to the power plant? (b) If we still assume a 2-sided, 5% level test, the same exposure probability among controls, same OR, and equal numbers of cases and controls, what will the sample size need to be to have a power of 80%? (c) Since investigators find it very difficult to recruit cases, they decide to recruit three times as many…Using python programming language i.e. (Anaconda - Jupyter )According to a study exactly 12 % of gift cards purchased from e-commerce portals are never used. The manager of an e-commerce company wanted to test whether this claim is true. She collected data of 250 gift card purchases and found that 22 gift cards were not used till its expiry date. (a) Conduct an appropriate hypothesis test at 5% significance to check whether the claim that exactly 12% gift cards are never used is true or not. (b) Calculate the 95% confidence interval for the proportion of gift cards that are not used.
