Hello, I'm having trouble calculating the pooled sample porportion
The purchasing department has suggested your company switch to a new hybrid tablet and laptop. As CEO, you want data to be assured that employees will like these new hybrids over the old laptops. You designate the next 14 employees needing a new laptop to participate in an experiment in which seven will be randomly assigned to receive the standard laptop and the remainder will receive the new hybrid tablet and laptop. After a month of use, these employees will express their satisfaction with their new computers by responding to the statement "I like my new computer" on a scale from I to 5, where 1 represents "strongly disagree, 2 is "disagree," 3 is "neutral," 4 is "agree," and 5 is "strongly agree." The employees with the hybrid computers have an average satisfaction score of 4.3 with standard deviation 0.3. The employees with the standard laptops have an average of 3.5 with standard deviation 0.9. Give a 95% confidence interval for the difference in the mean satisfaction scores for…
Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 490 were in favor, 398 were opposed, and 119 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 119 subjects who said that they were unsure, and use a 0.01 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. H0: p=0.5 H1: p<0.5 B. H0: p=0.5 H1: p>0.5 C. H0: p≠0.5 H1: p=0.5 D. H0: p=0.5 H1: p≠0.5 Identify the test statistic for this hypothesis test. The test statistic…
The state of Georgia's HOPE scholarship program guarantees fully paid tuition to Georgia public universities for Georgia high school seniors who have a B average in academic requirements as long as they maintain a B average in college. It was reported that 73 out of the 137 randomly selected students entering Ivan Allen College at Georgia Tech (social science and humanities) with a HOPE scholarship lost the scholarship at the end of the first year because they had a GPA of less than 3.0. It was also reported that 72 of a random sample of 111 students enterin the College of Computing with a B average had lost their HOPE scholarship by the end of the first year. Is there convincing evidence that the proportion who lose HOPE scholarships is different for the College of Computing than for the Ivan Allen College? (Use the 4-step process) State: Plan: Do: Conclude: b)Given your conclusion above, which type of error, Type I or Type II, is it possible to make? Describe that error in the…
The National Academy of Science reported that 37% of research in mathematics is published by US authors. The mathematics chairperson of a prestigious university wishes to test the claim that this percentage is no longer 37%. He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 221 recent articles published by reputable mathematics research journals and finds that 98 of these articles have US authors. Does this evidence support the mathematics chairperson’s claim that the percentage is no longer 37%? Use a 0.05 level of significance. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
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 91 people were asked the voter registration question face to face. Of those sampled, seventy respondents gave accurate answers (as verified by city records). Another random sample of 95 people were asked the same question during a telephone interview. Of those sampled, seventy-three respondents gave accurate answers. Assume the samples are representative of the general population. (a) Categorize the problem below according to parameter being estimated, proportion p, mean μ, difference of means μ1 – μ2, or difference of proportions p1 – p2. Then solve the problem. pμ1 – μ2 μp1 – p2 (b) Let p1 be the population proportion of all people who answer the voter registration question accurately during a face-to-face interview. Let p2 be the population…
If I randomly draw a card from a standard deck of cards 50 different times and guess the suit correctly 15 times. what conditions would I have to check in step 2 of a hypothesis test to see if I am statistically better than the average of 25%.
The National Academy of Science reported that 31 % of research in mathematics is published by US authors. The mathematics chairperson of a prestigious university wishes to test the claim that this percentage is no longer 31 %. He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 188 recent articles published by reputable mathematics research journals and finds that 74 of these articles have US authors. Does this evidence support the mathematics chairperson's claim that the percentage is no longer 31 % ? Use a 0.02 level of significance.

Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 481 were in favor, 404 were opposed, and 118 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 118 subjects who said that they were unsure, and use a 0.05 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho p=0.5 H₁ p.5 OB. Ho p=0.5 H₁ p<0.5 OC. Ho: p0.5 H₁ p=0.5 OR H. p=05 C

The Mayoral challenger claims that less than 30% of residents over the age of 25 have bachelor's degrees in our city. To test this claim, you survey 80 adults over the age of 25 and find only 18 possess bachelor's degrees. At the 5% level of significance, is there enough evidence to support the challengers claim?
