According to recent study. 160 of 496 technology CEOS from around the world responded that technological advances will transform their business and 77 responded thatresource scarcity and cimate change will transform their business. Complete parts (a) through (c) below.a. Construct a 90% confidence interval estimate for the population proportion of tech CEOS who indicate technological advances as one of the global trends that will transformtheir business.(Round to four decimal places as needed.)

We have given that, Favorable cases (X) = 160 and sample size (n) = 496 Then, We will find 90%…

The Federal Bureau of Investigation (FBI) compiles data on crimes and crime rates and publishes the information in Crime in the United States. A violent crime is classified by the FBI as murder, forcible rape, robbery, or aggravated assault. The first two columns of Data set 1 give a relative-frequency distribution for (reported) violent crimes in the year 2010. A random sample of 500 violent-crime reports from last year yielded the frequency distribution shown in the first and third columns of Data set 1. At the 5% significance level, do the data provide sufficient evidence to conclude that last year's violent-crime distribution is different from the 2010 distribution?

A statistics student seeking part-time employment as a New York City cab driver is trying to decide between driving a yellow cab or a green cab and examines tip amounts to help in making the decision. Using data from the New York City Taxi & Limousine Commission (http:// www.nyc.gov/html/tlc/html/about/trip_record_data.shtml), the stu- dent examines tip amounts from 25 randomly selected green cab fares and tip amounts from 25 randomly selected yellow cab fares.

Chapter 6, Section 3-CI, Exercise 148 Metal Tags on Penguins and SurvivalA study was designed to test whether applying metal tags is detrimental to a penguin. One variable examined is the survival rate 10 years after tagging. The scientists observed that 10 of the 50metal tagged penguins survived, compared to 18 of the 50 electronic tagged penguins. Construct a 90% confidence interval for the difference in proportion surviving between the metal and electronic tagged penguins (pM-pE). Let pM be the proportion of penguins with metal tags that survived and pE be the proportion of penguins with electronic tags that survived.Round your answers to three decimal places.The 90% confidence interval is to .
You may need to use the appropriate appendix table or technology to answer this question. A survey asked senior executives at large corporations their opinions about the economic outlook for the future. One question was, "Do you think that there will be an increase in the number of full-time employees at your company over the next 12 months?" In the current survey, 228 of 400 executives answered Yes, while in a previous year survey, 176 of 400 executives had answered Yes. Provide a 95% confidence interval estimate for the difference between the proportions at the two points in time. (Use current year previous year. Round your answer to four decimal places.) to What is your interpretation of the interval estimate? The 95% confidence interval ---Select--- ✓zero. This suggests that the proportion of executives who are predicting an increase in full- time jobs for the current year is ---Select--- ✓ than the proportion of executives who were predicting an increase in full-time jobs for the…
A warden is motivated to reduce to aggressive interactions between inmates that sometimes occur in common areas like the yard. He tasks you, the prison psychologist, to find out what can be done to reduce aggressive behavior. Having known the prisoners, you hypothesize that there must be a relation between aggressiveness and having something to keep oneself busy. You get 10 volunteer inmates and give them a scale of aggression and then ask how many hours a week on average they spend with a hobby.The data in z-scoresare: C. Your spouse is a teacher at a highschool. You convince them to run the same scales on some of their students and the r value is .42. At ?=.01is that significantly different than for the one for the inmates?
When you hold the mouse pointer over a point on the graph, the specific value corresponding to that point appears (e.g., “California, 2013 - 19.4%”) as well as a line called “90% Confidence” followed by an range of values. Generally speaking, what does the range of values denoted by “90% Confidence” indicate?
8.2 Question 3). According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, Arkansas had 1,601 complaints of identity theft out of 3,482 consumer complaints ("Consumer fraud and," 2008). Calculate a 90% confidence interval for the proportion of identity theft in Arkansas.
8.2 question 5). In 2013, the Gallup poll asked 1,039 American adults if they believe there was a conspiracy in the assassination of President Kennedy and found that 634 believe there was a conspiracy ("Gallup news service," 2013). Estimate the proportion of American’s who believe in this conspiracy using a 98% confidence interval.
