It is believed that 11% of all Americans are left-handed. A college needs to know how many left-handeddesks to place in the big lecture halls being constructed on its campus. In a random sample of 210 studentsfrom that college, whether or not a student was left-handed was recorded for each student. The collegewants to know if the data provide enough evidence to show that students at this college have a higherpercentage of left-handers than the general American population? State the random variable, populationparameter, and hypotheses. State the Type I and Type II errors in the context of this problem.

The following table gives the proportion of samples of college students in Washington as compared to Texas who support the idea of mandatory mental health counseling once a week for all college students for one year as a prerequisite to graduate with a degree.

Suppose you just graduated with an accounting degree and are trying to choose an accounting firm to begin your career. You spent hours researching many firms and have narrowed your search down to three (i.e. Aguilar, Brown and Cheng). You have surveyed accountants to determine if the average incomes at each firm are equal between each of your top three choices. Obviously you want to join the firm with the highest average pay. Below are a sample of salaries (i.e. eight individuals from each firm) enabling you to test the hypothesis that the average pay (in thousands of $) is equal between employers. Use Fisher's LSD procedure (if necessary) to test whether there is a significant difference between any of the firms.

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 212 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 0.10 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 H, and the alternative hypothesis H₁.

In the twentieth century, it was a common practice in Southern California for houses to be built with pools in the backyard. For new homes, however, that practice may be changing, possibly as a measure to help reduce climate change. A recent study examined a random sample of 132 houses built in Southern California in the twentieth century and an independent, random sample of 88 new houses built in Southern California. The sample of twentieth century houses contained 76 houses with pools, and the sample of new houses contained 34 houses with pools.Based on this survey, can we conclude, at the 0.01 level of significance, that the proportion p1 of all Southern California twentieth century houses that were built with pools is greater than the proportion p2 of all new Southern California houses that were built with pools? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the…
Are American men or women more into online dating? Researchers from a pop culture magazine conducted a study to see if there is a difference in the proportion of men and women under 30 that use online dating sites. They collected independent random samples of 96 women and 88 men, ranging from 18-30 years old, from across the US. Of the women, 67 reported using online dating sites, while 62 of the men reported using online dating sites. Assume the subjects responded honestly. What would be the test statistic and P-value for performing a hypothesis test Ho : P1 = P2 vs. HA : P1 + P2 ? Select one: O a. z =-0.098 ; P-value = 0.9204 O b. z =-1.13 ; P-value = 0.1292 O c. z =-3.77 ; P-value is approximately 0 O d. z =-0.098 ; P-value = 0.4602 O e. z =-1.13 ; P-value = 0.2594 Clear my choice
Your statistics instructor claims that 60 percent of the students who take her Elementary Statistics class go through life feeling more enriched. For some reason that she can't quite figure out, most people don't believe her. You decide to check this out on your own. You randomly survey 55 of her past Elementary Statistics students and find that 29 feel more enriched as a result of her class. Now, what do you think?

Hypertension is when an adult is classified as having high blood pressure (above 130 systolic blood pressure is considered hypertension). Researchers want to know the proportion of adult North Americans (above age of 18) that have hypertension. Based on a study of 3532 adult North Americans, 1219 of them were classified as having hypertension.
You may need to use the appropriate technology to answer this question. Suppose a company surveyed the work preferences and atitudes of 1,006 working adults spread over three generations: baby boomers, Generation X, and millennials. In one question, individuals were asked if they would leave their current job to make more money at another Job. The sample data are summarized in the following table. Generation Leave Job for More Money? Baby Boomer Generation X Millennial Yes 124 154 167 No 202 185 174 Conduct a test of independence to determine whether interest in leaving a current job for more money is independent of employee generation State the null and aiternative hypotheses Hg Interest in leaving job for more money is independent of the employee generation H, Interest in leaving job for more money is not independent of the employee generation.
