The Diversity, Equity, and Inclusion (DEI) office of a major multinational bank is investigating the process used to makerecent hires for financial analysts. The office knows that exactly 12% of all applications were from minority candidates andthat exactly 10% of the open positions were filled by members of a minority.For the investigation, the DEI office will take a random sample of 1650 applications. Let p be the proportion of minorityapplicants in the sample.Answer the following. (If necessary, consult a list of formulas.)(a) Find the mean of p.(b) Find the standard deviation of p.(c) Compute an approximation for P≤0.1), which is the probability that there willbe fewer minority applicants in the sample than were hired by the bank. Roundyour answer to four decimal places.EspañolFS

Among college students, the proportion p who say they’re interested in their congressional district’s election results has traditionally been 75% . After a series of debates on campuses, a political scientist claims that the proportion of college students who say they’re interested in their district’s election results is more than 75% . A poll is commissioned, and 207 out of a random sample of 275 college students say they’re interested in their district’s election results. Is there enough evidence to support the political scientist's claim at the 0.01 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H0 and the alternative hypothesis H1 . H0: H1: (b) Determine the type of test statistic to use. ▼(Choose one) (c) Find the value of the test statistic. (Round…
The Pew Research Center Internet Project, conducted on the 25th anniversary of theInternet, involved a survey of 857 Internet users (Pew Research Center website, April 1,2014). It provided a variety of statistics on Internet users. For instance, in 2014, 87%of American adults were Internet users. In 1995 only 14% of American adults used theInternet.a. The sample survey showed that 90% of respondents said the Internet has been a goodthing for them personally. Develop a 95% confidence interval for the proportion ofrespondents who say the Internet has been a good thing for them personally.
Many states are carefully considering steps that would help them collect sales taxes on items purchased through the Internet. How many randomly selected sales transactions must be surveyed to determine the percentage that transpired over the Internet? Assume that we want to be 99% confident that the sample percentage is within two percentage points of the true population percentage for all sales transactions. n = (Round up to the nearest integer.)
In 1942, an organization surveyed 1100 adults and asked, "Are you a total abstainer from, or do you on occasion consume, alcoholic beverages?" Of the 1100 adults surveyed, 440 indicated that they were total abstainers. In a recent survey, the same question was asked of 1100 adults and 418 indicated that they were total abstainers. Complete parts (a) and (b) below. (a) Determine the sample proportion for each sample. and respectively. The proportions of the adults who took the 1942 survey and the recent survey who were total abstainers are (Round to three decimal places as needed.)
The Institute of Education Sciences measures the high school dropout rate as the percentage of 16- through 24-year-olds who are not enrolled in school and have not earned a high school credential. In 2009, the high school dropout rate was 8.1%. A polling company recently took a survey of 1000 people between the ages of 16 and 24 and found 6.5% of them are high school dropouts. The polling company would like to determine whether the dropout rate has decreased at a 5% significance level. reject HO we can conclude that the high school dropout rate has decreased reject HO we cannot conclude that the high school dropout rate has decreased do not reject HỒ we cannot conclude that the high school dropout rate has decreased do not reject HỒ we can conclude that the high school dropout rate has decreased
