You are buying a rubber gasket seal for a compartment of a rocket carrying people. The quality of the gasket seal is in question, as gasket failure may mean loss of lives. Your decision to buy the gasket from a vendor will have Type I (a) and Type II (B) errors. Which error will you be more careful about and why? Answer here---> What are the two ways to reduce Type II (B) error in hypotheses testing? Answer here--->

A medical researcher wishes to try three different techniques to lower cholesterol levels of patients with high cholesterol levels. The subjects are randomly selected and assigned to one of three groups. Group 1 is given medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six weeks, each subject's cholesterol level is recorded. Test the hypothesis that there is no difference among the means. Use a= 0.05
Solve this problem using Sensitivity analysis/ report. The JAV Company manufactures two types of lamps; Special lamp and regular lamp. Each special lamp requires 4 pounds of brass and each regular lamp requires 8 pounds of brass. During each production period, the company's brass supply limited to 640 pounds. Each special lamp requires 6 hours of milling time in the machines and each regular lamp requires 2 hours of milling time in the machine, The company's machine are available only for 360 hours in each production period. Each special lamp requires 5 light bulbs that must be imported from Hongkong. The importation of these bulb is limited to 200 units. The contribution to profit of each special lamp and regular lamp are P400 and P360 respectively. How many units of the special lamp and regular lamp should be produced per production period in order to maximize the profit? b) what will happen happen to the optimal solution if the unit profit on y decreases by 230? c) What will happen…

A researcher is interested in the effect of the pandemic on social media use among college students. The researcher hypothesizes that college students spend more time on social media thanthey did before the pandemic. To test his hypothesis, he randomly selected 50 college students and asked how many hours do they spend on social media per day before and after the pandemic. a) What is the research question? b) What is/are the variable(s)? What graphs can be used to display the variable(s) visually? c) What statistical test can be used to answer the research question?
commonly cited standard for one-way length (duration) of school bus rides for elementary school children is 30 minutes. A local government office in a rural area conducts a study to determine if elementary schoolers in their district have a longer average one-way commute time. If they determine that the average commute time of students in their district is significantly higher than the commonly cited standard they will invest in increasing the number of school busses to help shorten commute time. What would a Type 2 error mean in this context? The local government decides that the average commute time is 30 minutes. The local government decides that the data provide convincing evidence of an average commute time higher than 30 minutes, when the true average commute time is in fact 30 minutes. The local government decides that the data do not provide convincing evidence of an average commute time higher than 30 minutes, when the true average commute time is in fact higher than 30…

The term 'Boomerang Generation' refers to the recent generation of young adults who have had to move back in with their parents. In a 2012 survey, 198 out of 801 randomly selected young adults (ages 18-34) had to move back in with their parents after living alone. In a similar survey from the year 2000, 284 out of 1811 young adults had to move back in with their parents. The table below summarizes this information. The standard error (SE) is given to save calculation time. year total # who moved back (xx) total # in survey (nn) proportion p^=x/np^=x/n 2012 198 801 0.247191011235955 2000 284 1811 0.156819436775262 Standard Error: SE = 0.0164608118673214 Test the claim that a greater proportion of all young adults moved back in with their parents in 2012 than in 2000.

A media personality argues that global temperatures are not rising, because every year an increase is reported, such as 0.09 degrees C. The difference from the previous year is less than the margin of error of about 0.13 degrees C, so that difference should be ignored. What is a strong counter argument? The difference is only 0.4 but that is still a significant change. The change of 0.9 is not a lot and thus should be ignored. The margin of error is larger than the increase so we should consider it an issue just extra information and thus can be ignored. The margin of error is quite small compared to the change year over year, so it is a significant issue.
