The magazine Tech Worx reported that 89% of software engineers rate the company they work for as "a great place to work." As a veteran headhunter with extensive experience in the tech industry, you claim the percentage given in the report is not correct. You will test your claim by performing a hypothesis test. To do so, you survey 225 randomly chosen software engineers. Of those surveyed, 216 rated the company they work for as "a great place to work."

A recent public survey asked the following question. "Many people believe this playground is too small and in need of repair. Do you think the playground should be repaired and expanded even if that means raising the entrance fee to the park?" Describe two ways this question may lead to response bias. *** 00000 Select all that apply. A. The question mentions higher fees, which could make people reject improvements to the playground. B.

In the Texas senate races, a candidate must clear 50% to avoid a runoff election. In a recent poll of 1040 voters in Texas, 51% of voters preferred candidate. We will a hypothesis test to see if we can say at the 5% significance level that more than 50% of voters in Texas prefer candidate based on this poll. State the null and alternative hypothesis. Find the test-statistic. Find the P-value. Make a conclusion. Interpret your answer.
Data for a certain community show that 18% of the adult residents are German. Suppose 74 people are called for jury duty and only 12 of them are German. Does this apparent underrepresentation of Germans call into question the fairness of the jury selection system? Explain. Write appropriate hypotheses. H0: ▼ p not equals 18 %p≠18% p equals 18 %p=18% p greater than 18 %p>18% p less than 18 %p<18% HA: ▼ p equals 18 %p=18% p not equals 18 %p≠18% p greater than 18 %p>18% p less than 18 %p<18% The test statistic is z=_______________ (Round to two decimal places as needed.) The P-value is _____________________ (Round to three decimal places as needed.) State your conclusion assuming a P-value smaller than 0.05 is significant.
A study considered the question, “Are you a registered voter?” Accuracy of response was confirmed by a check of city voting records. Two methods of survey were used: a face-to-face interview and a telephone interview. A random sample of 93 people were asked the voter registration question face-to-face. Seventy-nine respondents gave accurate answers. Another random sample of 83 people was asked the same question during a telephone interview. Seventy-four respondents gave accurate answers. Assume that the samples are representative of the general population. Test the claim that there is a difference in the proportion of accurate responses from face-to-face compared with telephone interviews. Use alpha=.05 What is the null hypothesis? What is the alternative hypothesis? What distribution are you using? What test are you running? What is your conclusion?
A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 3% margin of error at a 98% confidence level, what size of sample is needed? The political candidate will need to sample people.
A telecommunications company provided its cable tv subscribers with free access to a new channel for a month. It then chose a sample of 700 viewers and asked them whether they would be willing to pay an extra $10 per month to continue access to the channel. Total of 33 replied that they would be willing to pay. The marketing director of the company claims that more than 5% of all its subscribers would be willing to pay. Can you conclude that the directors claim is true? Use 0.01 level of significance.
