According to Padgett Business Services, 20% of all small-business owners say the most important advice for starting a business is to prepare for long hours and hard work. Twenty-five percent say the most important advice is to have good financing ready. Nineteen percent say having a good plan is the most important advice; 18% say studying the industry is the most important advice; and 18% list other advice. Suppose 14 small business owners are contacted, and assume that the percentages hold for all small-business owners.a. What is the probability that none of the owners would say preparing for long hours and hard work is the most important advice?b. What is the probability that six or more owners would say preparing for long hours and hard work is the most important advice?c. What is the probability that exactly five owners would say having good financing ready is the most important advice?d. What is the expected number of owners who would say having a good plan is the most important…

You may need to use the appropriate technology to answer this question. The American Association of Individual Investors (AAII) On-Line Discount Broker Survey polls members on their experiences with discount brokers. As part of the survey, members were asked to rate the quality of the speed of execution with their broker as well as provide an overall satisfaction rating for electronic trades. Possible responses (scores) were no opinion (0), unsatisfied (1), somewhat satisfied (2), satisfied (3), and very satisfied (4). For each broker summary scores were computed by calculating a weighted average of the scores provided by each respondent. Suppose a portion of the survey results follow. Brokerage Speed Satisfaction O Ho: B₁ * 0 Ha: B₁: = 0 Ho: B₁ ≥ 0 Ha: B₁ <0 Ho: B₁: Ha: B₁ * 0 = 0 |Ọ Ho: Bo #0 Ha: Bo = 0 A Ho: Po = 0 Ha: Bo # 0 B с D E F G H I J K 3.4 3.3 3.4 3.6 3.2 3.8 3.8 2.6 2.7 4.0 2.5 3.5 3.6 3.9 These ratings data on x = the quality of the speed of execution and y = overall…

A poll uses responses to several questions to calculate a "Happiness" index that measures overall happiness. An article included the happiness index for the 7 years between 2008 and 2016. Also included in the article were the percentages of people who responded "somewhat agree" or "strongly agree" to the following statements. Statement 1 (happy with life) 1: At this time, I'm generally happy with my life. Statement 2 (won't benefit): I won't get much benefit from the things that I do anytime soon.

Having a brother increases one's monthly earnings by $200." Why is this an example of an incomplete causal statement?

As you read about each​ study, (a) classify the type of research that it​ reflects, and​ (b) identify the kinds of conclusions that might reasonably be drawn from the results. During their​ 8th- and​ 11th-grade school​ years, students in the Ranger School District take standardized achievement tests designed to assess their language and math skills. The superintendent receives a report showing how Ranger students compare with those in many other school districts across the nation. The superintendent discusses the results with the school principals. ​(a) Classify the research as one of the​ following:   ​Quantitative/descriptive   ​Quantitative/correlational   ​Quantitative/experimental   ​Quantitative/quasi-experimental   Qualitative   Mixed​ methods, and then ​(b) Identify one or more conclusions that might reasonably be drawn from this study​ and, if​ relevant, one or more conclusions that cannot be drawn from the study
