Several of the U.S. occupations that are projected to have the fastest job growth during the decade of the 2020’s are in either the medical or the renewable energy sectors of the economy. For example, the Federal Bureau of Labor Statistics (BLS) projects that “wind turbine service technicians” will be the fastest growing occupation during the decade, with an expected growth rate of 64% after 10 years. “Solar panel installers” is projected to be the third-fastest growing occupation, with an expected growth rate of 51% . Meanwhile, “nurse practitioners” ( projected growth), “occupational therapy assistants” (35% projected growth), and “home health and

An October 26, 2020 news report raised alarms that the population of North Atlantic Right Whales had declined a dramatic 11% with increased risk for the whales extinction in the near future. Whale deaths are largely caused by collisions with fishing boats and by whale entanglement in fishing nets and lobster trap gear.  “Since the population peaked at 481 whales in 2011, there have been 103 births, but roughly 218 whales have died, presumably because of human activity – a rate of 24 deaths per year.”  Subtracting births from death, what is the yearly net decrease in the Right Whale population between 2011 and 2020?  Create a linear mathematical model for the decline in Right Whale population since 2011 (i.e. let 2011 be year zero).  The article says that in 2018 there were 366 Right Whales counted.  How accurate is your linear model when compared to the 2018 whale count?

Personal care aide is an occupation that is growing quickly. Assume​ that, in a certain​ region, there will be a need for 195,686 personal care aides in​ 2024, a growth of about 29​% over 2014 levels. How many personal care aides were there in this region in​ 2014?

.A new, miracle diabetes drug that diminishes major symptoms of diabetes has been approved by the FDA. Health care professionals and researchers believe that the new drug will prolong lifespan of diabetes patients. If the population is in steady state and the incidence is constant, what will the effect of this new drug be on the prevalence of diabetes in the population? Explain.

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.A sample of 80 stocks traded on the NYSE that day showed that 11 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly less than 0.3. You use a significance level of α=0.02α=0.02.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = The p-value is... less than (or equal to) αα greater than αα This test statistic leads to a decision to... reject the null accept the null fail…

If actual period demand varies from the forecast by more than 3MAD, this indicates: there is 3% chance that the forecast is wrong. there is a 98% chance that the forecast is wrong. there is a 97% chance that the forecast is wrong. there is a 3% chance that the forecast is correct Moving to the next question prevents changes to this answer:

A Northwest Airlines ticket counter forecasts that 40 people per hour will need to check in. It takes an average of 1.2 minutes to services a customer. Assume that interarrival times and  service times are exponential and that all customers wait in a single line for the first avaliable agent. If we want the average time a customer spends in line and in service to be 4 minutes or less, how many ticket agents should be on duty?

In a certain year, it was estimated that 1,000,000 of the 307,000,000 residents of the United States are HIV-positive. (HIV is the virus that is believed to cause AIDS.) The Repeatedly Reactive Immunoassay (RRIA) diagnostic test correctly diagnoses the presence of AIDS/HIV 99.7% of the time and correctly diagnoses its absence 98.5% of the time. (Round your answers to four decimal places.) (a) Find the probability that a person whose test results are positive actually has HIV.(b) Find the probability that a person whose test results are negative does not have HIV.(c) Find the probability that a person whose test results are positive does not have HIV.(d) Find the probability that a person whose test results are negative actually has HIV.(e) Which of the probabilities would you be interested in if you or someone close to you tested positive? the probability that a person whose test results are positive actually has HIVthe probability that a person whose test results are negative does not…

cipate worth S Exercise 2.9.8. [S][Section 2.1][Goal 2.1][Goal 2.5] Counting red blood cells. On page 240 of the April 2011 issue of the Bulletin of the American Mathematical Society Misha Gromov wrote that Erythrocytes are continuously produced in the red bone marrow of large bones... at the rate ~ 2.5 million/second or~ 200 billion/day. Adult humans have 20-30 trillion erythrocytes,~ 5 million/ cubic millimeter of blood. [R54] (a) What is an erythrocyte? (b) Check that 2.5 million/second is about 200 billion/day. (c) Use the numbers in the second sentence to estimate the volume of blood in an adult human, in liters. (d) Check your answer to the previous question with a web search.
