n a certain California city, projections for the next year are that there is a 20% chance that electronics jobs will increase by 200, a 50% chance that they will increase by 300, and a 30% chance they will decrease by 800. What is the expected change in the number of electronics jobs in that city in the next year?

Helena gathers data about the music preferences of users of a social media application. She gathers information on music events (MEs). In her study, a music event is defined as a posting that has a hashtag or is linked to other video- sharing websites. 1. From her data, Helena claims that about 15% of MEs on the application are hip hop/rap. Juan wants more proof of her claim. • Juan uses technology to determine the genres of music of 100 MEs he chooses at random. He determines that 9 were hip hop/rap. • Juan points out the 9% rate to Helena. Part A Assume Helena is correct and 15% of MEs on the app are hip hop/rap. Use random numbers and a simulated sampling distribution to simulate the outcome of several trials, in which each trial samples 100 MEs from the app and counts the number of hip hop/rap MEs. Make a histogram for your data. Is the model consistent with what you would expect? Explain.
A researcher wondered whether there was a relationship between age group (adolescents, young adults and adults) and views about the future (positive views, neutral views or negative views). Participants from each age group answered a questionnaire testing their views about the future and based on their score they were categorized as having either positive views, neutral views or negative views. Out of 1000 participants, 250 were adolescents, 450 were young adults and 300 were adults; Of all the participants, 200 had positive views, 500 had neutral views and 300 had negative views.a. Complete the expected frequencies in the following table. Adolescents Young adults AdultsPositive viewsNeutral views Negative views
College instructors who adopt this book are (we hope!) twice as likely to continue to use the book the following year as they are to drop it, whereas nonusers are four times as likely to remain nonusers the following year as they are to adopt this book In the long term, what proportion of college instructors will be users of this book?
Cigarettes 2009. In 1999, the Centers for Disease Controland Prevention estimated that about 34.8% of high schoolstudents smoked cigarettes. They established a nationalhealth goal of reducing that figure to 16% by the year2010. To that end, they would be on track if they achieveda reduction to 17.7% by 2009. In 2009, they released aresearch study in which 19.5% of a random sample of5080 high school students said they were current smokers.Is this evidence that progress toward the goal is off track?a) Write appropriate hypotheses.b) Verify that the appropriate assumptions are satisfied.c) Find the P-value of this test.d) Explain what the P-value means in this context.e) State an appropriate conclusion.f) Of course, your conclusion may be incorrect. If so,which kind of error did you commit?
A poll in June 2020 found that 83% of American parents believe that virtual learning instead of in- person learning widens the equity gap for students. A later poll in October 2020 asked 1025 American parents if they believe virtual learning instead of in- person learning widens the equity gap for students, and found that 820 believe that yes, virtual learning instead of in-person learning widens the equity gap for students. Does this mean that the proportion of American parents, who believe that virtual learning instead of in-person learning widens the equity gap for students, has decreased? Test at the 10% significance level. State the hypotheses. Но: р (? На: р (? Calculate the sample proportion. Round to four decimal places. Calculate the test statistic. Round to two decimal places.

.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.
Previously, De Anza's statistics students estimated that the amount of change daytime statistics students carry is exponentially distributed with a mean of $0.88. Suppose that we randomly pick 25 daytime statistics students. Find the probability that an individual had between $0.80 and $1.00. Graph the situation, and shade in the area to be determined.

not A 1995 study by the School of Public Health reported that 87% of male students who live in a fraterity house are binge drinkers. The figure for fraternity members who are residents of a fraternity house is 71 %, while the figure for men who do not belong to a fraternity is 44 % Suppose that 11% of U.S. male students live in a fraternity house, 15% belong to a fraterity but do not live in a fraterity house, and 74% do not belong to a fraterity a. What is the probability that a randomly selected malp student is a binge drinker? b. If a randomly selected male student is a binge drinker, what is the probability that he lives in a fraterity house? The probability that a randomly selected male student is a binge drinker is 0.5509 (Type an integer or a decimal rounded to two decimal places as needed) CETTE

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.)

It is known that in any given year, • 90% of the people in a city move to the suburbs; • 80% of the people in the suburbs do not move to the city. Given an initial city population of 55,000 and an initial suburb population of 77,000, what are the long-term population levels of the city and the suburb?
