Suppose the following table was generated from a sample of 20 CEOS relating annual salary to years of experience and the industry in which they are employed. Indicator(dummy) variables were created for each industry (1 if the CEO works in that industry, 0 otherwise). The Financial industry is considered the base-level industry.CoefficientsStandard Errort StatP-ValueIntercept140317.2005123499.35974140.0979640.000000Experience3151.954512159.66997419.7404340.000000Health Care9587.5125723934.1074612.4370240.027739Manufacturing - 23861.9862733823.687525- 6.2405690.000016Service15458.5651693810.8643914.0564460.001034Copy DataAccording to the results, if a CEO in the Financial industry and a CEO in the Service industry both have 25 years of experience, what is the estimated difference in annualsalary between the two CEOS?

The National Assessment of Educational Progress (NAEP) includes a mathematics test for eighth‑grade students. Scores on the test range from 00 to 500.500. Demonstrating the ability to use the mean to solve a problem is an example of the skills and knowledge associated with performance at the Basic level. An example of the knowledge and skills associated with the Proficient level is being able to read and interpret a stem‑and‑leaf plot. In 2019, 147,400147,400 eighth‑graders were in the NAEP sample for the mathematics test. The mean mathematics score was ?⎯⎯⎯=282.x¯=282. We want to estimate the mean score ?μ in the population of all eighth‑graders. Consider the NAEP sample as an SRS from a Normal population with standard deviation ?=40. According to the 9595 part of the 68-95-99.768-95-99.7 rule, 95%95% of all values of ?⎯⎯⎯x¯ fall within how many points on either side of the unknown mean ??μ? Give your answer to four decimal places.

Suppose researchers at an abdominal transplant clinic are concerned about the rate of graft loss due to diabetes status prior to receiving a donor kidney. Research has shown that gender discordance, or receiving a gender from a donor of an opposite gender may increase the risk of both exposure and outcome after transplant.

In 2001, the polls found that 81% of American adults believed that there was a conspiracy in the death of President Kennedy. Assume a recent poll asked 1160 American adults if they believe there was a conspiracy in the assassination and it found that 897 believe there was a conspiracy. Does the data show that the proportion of Americans who believe in this conspiracy is now lower? Test at the 9% level. What is the correct parameter symbol for this problem? What is the wording of the parameter in the context of this problem? Fill in the correct null and alternative hypotheses:

The personality characteristics of business leaders (e.g., CEOS) are related to the operations of the businesses that they lead (Oreg & Berson, 2018). Traits like openness to experience are related to positive financial outcomes and other traits are related to negative financial outcomes for their businesses. Suppose that a board of directors is interested in evaluating the personality of their leadership. Among a sample of n = 16 managers, the sample mean of the openness to experiences dimension of personality was M = 4.50. Assuming that u = 4.24 and o = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with a = .05 to test the hypothesis that this company's business leaders' openness to experience is different from the population.
