Of the good workers, 70% pass it, 40% of the poor workers pass it. Assume that these figures will hold true in the future. If the company makes the test part of its hiring procedure and only hires people who meet the previous requirements and also pass the test, what percent of the new Purchase Options Discussions hires will turn out to be good workers?

- A scientist is skeptical of a new pill that claims to “improve memory and concentration.” He finds 230 people and randomly assigns half to take the new pill and the other half to take a placebo pill that looks, smells, & tastes like the real thing. All the participants took learning & memory tests before the study and again, 6 weeks later. The scientist hired graduate students to administer & score the tests in his place. Select all of the words that describe this study.(ONLY NAME NO DESCRIOPTION ) Controlled Blind Placebo Observational Experiment Stratified Double-Blind RandomizedAir Passengers' Complaints In recent months, airline passengers have expressed much more dissatisfaction with airline service than ever before. Complaints include flight delays, lost baggage, long runway delays with little or no onboard service, overbooked flights, cramped space due to fuller flights, canceled flights, and grumpy airline employees. A majority of dissatisfied fliers merely grin and bear it. In fact, in the mid-19905, the average number of complaints per 100,000 passengers boarded was only 0.66. For several years, the average number of complaints increased to 0.74, 0.86, 1.08, and 1.21. In 2014, according to the Department of Transportation, the industrywide figure is an average of 1.34 complaints per 100,000 passengers. Alaska Airlines had the fewest average number of complaints per 100,000 with 0.42, followed by Southwest Airlines with 0.53. Frontier Airlines had the highest average number of complaints per 100,000 with 3.91 followed by United Airlines with 2.71.…A survey of 100 students asked them about the lunch room meals they liked: 42 students liked chicken fingers 60 liked pizza 47 liked hamburgers 22 liked chicken fingers and pizza 26 liked pizza and hamburgers 15 liked chicken fingers and hamburgers 8 students liked all three meals How many students didn't like any of these three meals? Briefly explain your reasoning.
- You may need to use the appropriate appendix table or technology to answer this question. Minnesota had the highest turnout rate of any state for the 2016 presidential election.t Political analysts wonder if turnout in rural Minnesota was higher than turnout in the urban areas of the state. A sample shows that 669 of 892 registered voters from rural Minnesota voted in the 2016 presidential election, while 414 out of 575 registered voters from urban Minnesota voted. (a) Formulate the null and alternative hypotheses that can be used to test whether registered voters in rural Minnesota were more likely than registered voters in urban Minnesota to vote in the 2016 presidential election. (Let P1 = the population proportion of voters in rural Minnesota who voted in the 2016 election and p₂ = the population proportion of voters in urban Minnesota who voted in the 2016 election.)

Mushrooms, however, are able to absorb and accumulate cad- mium at high concentrations. The Czech and Slovak governments have set a safety limit for cadmium in dry vegetables at 0.5 part per million (ppm). M. Melgar et al. measured the cadmium levels in a random sample of the edible mushroom Boletus pinicola and pub- lished the results in the paper "Influence of Some Factors in Toxi- city and Accumulation of Cd from Edible Wild Macrofungi in NW Spain" (Journal of Environmental Science and Health, Vol. B33(4), pp. 439-455). A hypothesis test is to be performed to decide whether the mean cadmium level in Boletus pinicola mushrooms is greater than the government's recommended limit.

ALSO DRAW THE DECISION TREEAfter the premiere of the new comedy Bumblebee, moviegoers were asked in a quick poll whether they liked the movie. Out of 50 adults, all but 17 said they liked the movie, whereas out of 100 teenagers, all but 49 said they liked the movie. Fill in the blanks below to make the most reasonable statement possible.

X 5Meaning-making is "an active process through which people revise or reappraise an event or a series of events" (Baumeister & Vohs, 2002, p. 613). When people find meaning in their lives, it leads to benefits such as affirmed self-worth, the opportunity to appreciate one's accomplishments and personal beliefs, and even improved physical health. Researchers study meaning-making in a variety of ways, including through verbal interviews with participants, and asking them to write narratives of their lives. In this study, you want to see which method will elicit meaning-making more successfully in the middle of the COVID- 19 pandemic. You divide a total of 21 participants into 3 conditions: a verbal phone interview about their life and experiences in the pandemic, a written narrative task about their life and experiences in the pandemic, and a control condition with neither task. Afterwards, participants answer a scale measuring meaning in life (higher score = more meaning). Participants'…
