A political pollster is conducting an analysis of sample results to make predictions on election night. In a two-candidate election, if a specific candidate receives at least 55% of the vote in the sample, that candidate will be forecast as the winner of the election. You select a random sample of 100 voters. Complete parts (a) through (c) below.a. What is the probability that a candidate will be forecast as the winner when the population percentage of her vote is 50.1%?The probability is 0.0980 that a candidate will be forecast as the winner when the population percentage of her vote is 50.1%.(Round to four decimal places as needed.)

A survey is conducted to determine if there is a Because the P-value of this test is large, there is not convincing evidence that the distribution of responses for the population of all students, parents, and teachers of this large high school differs. For which categories are the observed counts greater than expected? difference in the proportion of students, parents, and teachers who volunteer at least once a month. To investigate, a random sample of 45 students, 25 parents, and 12 teachers was selected from a large high school. The data are displayed in the tables. Observed counts: O There were more students than expected who do Student Parent Teacher Yes No not volunteer, and more parents and teachers than expected who do volunteer. 24 12 6 Volunteer? 21 13 6 There were more students than expected who do volunteer, and more parents and teachers than expected who do not volunteer.

In a city, according to a 1990 demographic report based on the census result, the average daily spending onfood per person is $75.In 2020, a random sample of 28 persons in the same city is selected and the daily spending ($) on food foreach interviewee is recorded as follow:55.0 59.5 62.5 65.5 68.5 69.0 70.0 70.0 82.0 82.583.5 85.0 86.0 86.5 86.5 87.0 87.0 87.0 89.0 92.593.0 94.5 94.5 96.0 98.0 102.5 108.5 110.5(a) Find the point estimate for the population mean daily spending on food per person in year 2020.(b) It is assumed that the spending is normally distributed. Construct a 90% confidence interval estimatefor the population mean daily spending on food per person in year 2020.(c) Is there sufficient evidence to conclude that the population mean daily spending on food per person in2020 is higher than 1990? Test at 1% level of significance. (State clearly the null hypothesis,alternatively hypothesis, rejection region, test statistics and conclusion.)

cording to a job website, each job opening on average attracted 251 résumés in 2016. The job market improved in 2017 compared to 2016, which means that more people will likely be switching jobs but also fewer nemploved workers remain in the job market. To find out which trend is stronger, a random sample of 20 employers in a region was taken. Each employer reported how many résumés they received in 2017 for each b opening. Their answers are shown in the accompanying table. Using a = 0.10, complete parts a through d. Click the icon to view the data on résumés received, a. State the null and alternative hypotheses. Determine the null hypothesis, Ho, and the alternative hypothesis, H,. Job Opening Data Ho: H = 251 * 251 210 208 (Type integers or decimals. Do not round.) 219 251 b.

The World Bank collects information on the life expectancy of a person in each country ("Life expectancy at," 2013) and the fertility rate per woman in the country ("Fertility rate," 2013). The data for 12 randomly selected countries for the year 2011 are shown in the table below. Table: Data of Fertility Rates versus Life Expectancy Fertility Rate Life Expectancy 1.7 77 5.8 55 2.2 70 2.1 76 1.8 75 2.0 78 2.6 73 1.5 81 6.9 54 2.9 72 4.7 63 6.8 57 The most commonly used type of correlation is Pearson correlation, named after Karl Pearson, introduced around the turn of the 20th century. Pearson's r measures the linear relationship between two variables, say X and Y. Find the Pearson’s correlation coefficient for the above data In reference to the calculated correlation coefficient above, describe the strength of the correlation.
