- People come to relationships with different attachment styles that partially stem from the attachments they experienced with the adults raising them and partially due to experiences in other relationships in their lives. Those who have what is known as “secure” attachments are comfortable with their partners emotions, can help soothe, and make movements towards the other person in a responsive way. Among a group of 10 individuals rated as having a secure attachment style, a researcher wanted to know if, as they were first being acquainted with another person, the amount of self-disclosure made them like their person more. The data is listed in Table 6 below. Test the hypothesis at an alpha of 0.05 (where increasing scores mean higher disclosure and higher liking). If you knew the new person you are about to go on a date with had a self-disclosure rating of 4, what would you predict your likeability score would be (provide the full regression formula as well as the response)? -use…People come to relationships with different attachment styles that partially stem from the attachments they experienced with the adults raising them and partially due to experiences in other relationships in their lives.

- An engineering company will hire new staff to develop new products, using production teams of engineers (core staff) and support staff on each team. Teams are labeled as: Design, Production, Analysis, Test. The core staff numbers in each team and the total number of engineers in each field to be recruited are as follows: Each design team consists of 2 Construction / environment, 4 Mechanical / design and 2 computer / software personnel; each production team consists of 3 construction/environmental, 0 mechanical/design and 6 computer/software personnel; and such that.)Accordingly, if x1, x2, x3 and x4 are the number of design, production, analysis and testing teams, respectively, find these values.Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correctsymbol (µ, p, Η) for the indicated parameter.

Use the parameter p, the true proportion of fireflies unable to produce light.Consider a screening system that analyzes the luggage that is being loadedto a plane. Each package first goes through a screening device. If it passes the test there, then it is loaded to the plane. If it does not, the package goes to a second screening device. The procedure is similar for the second device: if the luggage passes the test, it is loaded to the plane, if it fails, it issent to a third device. Packages that passes the test at third device are loladed to the plane, the ones that fail are taken paprt and not loaded to the plane.The screening devices i = 1; 2; 3 are not perfect. For each device, there are two risks:– With probability pi, each device erroneously passes a bag that is dangerous, given that previous devices have correctly rejected the bag.– With probability qi, each device erroneously fails a harmless bag that previous devices have also erroneously failed.Assume that pi; qi > 0 What is the probability that a dangerous package will be loaded to the aircraft?…
