A consulting group recently conducted a global survey of product teams with the goal of better understanding the dynamics of product team performance and uncovering the practices that make these teams successful. One of the survey findings was that 32% of organizations have a coherent business strategy that they stick to and effectively communicate. Suppose another study is conducted to check the validity of this result, with the goal of proving that the percentage is less than 32%. Complete parts (a) and (b) below. a. State the null and research hypotheses. Identify the null and alternative hypotheses. O A. Ho: as0.32; H,: a>0.32 O B. Ho: 120.32; H: <0.32 OC. Hoi a#0.32; H: =0.32 O D. Ho: 1=0.32; H4: n#0.32 b. A sample of 200 organizations is selected, and results indicate that 58 organizations have a coherent business strategy that they stick to and effectively communicate.

Caterpillar, Inc., manufactures and sells heavy construction equipment worldwide. The performance of Caterpillar’s stock is likely to be strongly influenced by the economy. For example, during the Great Recession, the value of Caterpillar’s stock plunged dramatically. Monthly data for Caterpillar’s risk-adjusted return (R − Rf) and the risk-adjusted market return (RM − Rf) are collected for a five-year period (n = 60). A portion of the data is shown in the accompanying table. (You may find it useful to reference the t table.)

2. A cohort study is conducted to assess the association between clinical characteristics and the risk of stroke. The study involves n = 1370 participants who are free of stroke at the study start. Each participant is assessed at study start (baseline) and every year thereafter for 5 years. The following data were collected relating hypertensive status measured at baseline to incident stroke over 5 years.

Q5: The theory that resistance by mosquitoes to an insecticide is due to a single dominant gene has been examined. Homozygous resistant mosquitoes were crossed with homozygous susceptible mosquitoes to give A heterozygous population. These were crossed to the homozygous susceptible population. Of this back cross progeny 465 were exposed to the insecticide, 264 died. Is the percentage killed significantly different to the percentage predicted by the model?

Example 5.1.7 A car-hire firm has two cars, which are hired out everyday. The number of demands for a car on each day is distributed as a Poisson distribution with mean 1.5. Calculate the proportion of days on which neither car is used and the proportion of days on which a demand cannot be met due to lack of cars [e15 = 0.2231].
Again recall Table 8a from the working paper "The Market for Financial Advisor Misconduct" discussed in Lecture 7 and HW 7. For your convenience, the table is reproduced below. Table 8a. Consequences of Misconduct: Industry and Firm Discipline No Misconduct Misconduct Remain with the Firm 81.29% 51.99% Leave the Firm 18.71% 48.01% Leave the Industry 8.92% 26.96% Join a Different Firm (within 1 year) 21.05% 9.79% Note: Table 8a displays the average annual job turnover among financial advisers over the period 2005-2015. The table shows, on average, the percentage of advisers that remain with their firm, leave the industry (for at least one year) or join a new firm (within a year). The job transitions are broken down by whether or not the advisor was disciplined for misconduct in the previous year. Consider randomly selecting five financial advisors who were disciplined for misconduct in the previous year. What is the chance that at least one of them leaves the firm? (Answer as a…
Beryllium is an extremely lightweight metal that is used in many industries, such as aerospace and electronics. Long-term exposure to beryllium can cause people to become sensitized. Once an individual is sensitized, continued exposure can result in chronic beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure to beryllium, workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, or normal). The results were as follows: Duration of Exposure <1 1 to <5 ≥5 Diseased 14 13 18 Sensitized 11 20 15 Normal 78 140 209 Test the hypothesis of independence. Use the a=0.10 level of significance and the P-value method with the TI-84 Plus calculator. What do you conclude? State the null and alternate hypotheses.
