A simple random sample of 450 residents in the state of New York is taken to estimate the proportion of peoplewho live within 1 mile of a hazardous waste site. If a 95% confidence interval were calculated for a scenariowhere p = 0.3 and another scenario where p = 0.7, how would the two confidence intervals compare?This cannot be determined from the information given.Since the sample proportion in the second scenario is larger, its confidence interval would be shifted to theright and narrower than the one calculated from the first scenario.Even though the sample proportions are different, the widths of the confidence intervals would be equal.Since the sample proportion in the first scenario is smaller, its confidence interval would be narrower.

The sample proportions are 0.3 and 0.7.

Medical professionals at a student health center are trying to alert the undergraduate population about the importance of getting sufficient sleep and the role this plays in their academic performance. The health center staff would like to estimate the true average amount of sleep that the undergraduate students are receiving and construct a 90% confidence interval for this estimate. Furthermore, in order to be useful, the interval can be no more than 1.6 hours WIDE ( so Margin or Error would be half of that). Table 1 reports the results from a pilot test that measured the amount of sleep obtained in a random sampling of undergraduate students. Use the standard deviation from this pilot study as your estimate for the population standard deviation.Table 1: Descriptive statistics for the sleep study Variable mean Std.Dev Hours of sleep 3.25 8.50 Based on the student health department's criteria, the number of students that should be selected is:
Suppose we know that a confidence interval for a population proportion is (0.105,0.355), with a sample proportion of p̂=0.23. What is the margin of error?
A random survey found that 220 out of 300 adults living in large cities (with populations of more than 1 million) wanted more state funding for public transportation. In small cities (with populations fewer than 100,000), 120 out 300 adults surveyed wanted more state funding. Call the population of adults living in large cities "Population 1" and the population of adults living in small cities "Population 2" while working these problems. With a 90% confidence level, what is the confidence interval for the difference in the population proportions? Give your answer to four decimal places.
Question 1: The GPAs of nursing students (p1) were compared to GPAs of student-athletes (p2) were compared. Of a sample of 400 randomly and independently selected nursing students, 75% were placed on honor roll. Of a sample of 100 athletes, 80% of the students were placed on honor roll. Calculated the LOWER bound of the 95% confidence interval for the two samples. Round to the nearest hundredth. Question 2: The GPAs of nursing students (p1) were compared to GPAs of student-athletes (p2) were compared. Of a sample of 400 randomly and independently selected nursing students, 75% were placed on honor roll. Of a sample of 100 athletes, 80% of the students were placed on honor roll. Calculated the UPPER bound of the 95% confidence interval for the two samples. Round to the nearest hundredth.

One company recently conducted a survey in which 420 women and 420 men were asked "Are you satisfied with the work of the Minister of Health?". Of these, 155 men and 118 women said they were satisfied with the minister's work. Assume that the experimental design was correct. Questions 1 and 2 cover this survey. 1. Find the upper limit of 95% confidence interval for the difference in the proportion of men and women who are happy with the work of the Minister (let men be group 1). 1. 0.03. 2. 0.09. 3. 0.15. 4. It is not possible to apply a normal approach and therefore we can not calculate the confidence interval. 2. What is the rejection area if it is to be examined whether the proportion of men and women who are satisfied with the job of Prime Minister is different (use a = 0.05)? 1. RejectHO efz 1.96. 2. Reject HO if z> 1.64. 3. RejectHO efz> -1.96 or <1.96. 4. Insufficient information provided to answer this.
Here are summary statistics for randomly selected weights of newborn girls: nequals 235 , x overbar equals32.8 hg, sequals 7.9 hg. Construct a confidence interval estimate of the mean. Use a 99 % confidence level. Are these results very different from the confidence interval 29.7 hgless than muless than35.3 hg with only 15 sample values, x overbar equals32.5 hg, and sequals 3.6 hg? What is the confidence interval for the population mean mu ? nothing hgless than muless thannothing hg (Round to one decimal place as needed.) Are the results between the two confidence intervals very different? A. No, because each confidence interval contains the mean of the other confidence interval. B. Yes, because one confidence interval does not contain the mean of the other confidence interval. C. No, because the confidence interval limits are similar. D. Yes, because the confidence interval limits are not…
If a sample of 35 employees had been selected, could we find a 95% confidence interval for the average salary of the entire company? O Yes because when I plug 35 into the calculator with the previous average of $55,000 and standard deviation of $5,000 I get a confidence interval of ($53,343.53, $56,656.47) No since 35 is less than 40.
The birth weights of a sample of newborns were recorded for a group born to mothers who did not get regular prenatal care (Group 1) and for a group born to mothers who did (Group 2). A 93% confidence interval for 41 – 2 was computed as follows: (-2.12 pounds, -0.89 pounds) Interpret the endpoints of this interval in the context of this problem. Do not use the word "difference" in your answer.
One method for measuring air pollution is to measure the concentration of carbon monoxide, or CO, in the air. Suppose Nina, an environmental scientist, wishes to estimate the CO concentration in Zagreb, Croatia. She randomly selects 45 locations throughout the city measures the CO concentration at each location. Based on her 45 samples, she computes the margin of error for a 95% t-confidence interval for the mean concentration of CO in Zagreb, in µg/m³, to be 4.28. What would happen to the margin of error if Nina decreases the confidence level to 90%? Nina increases the confidence level to 99%? Nina decreases the sample size to 33 locations? Nina increases the sample size to 65 locations? Answer Bank Increase Stay the same Decrease

Suppose the goal is to estimate the parameter stated in question 3 using a 95% confidence interval with margin of error no larger than 0.048. What is the minimum number of trick-or-treaters that would need to be selected to allow the calculation of a 95% confidence interval with margin of error no larger than 0.048? It can be assumed for this problem only that the proportion of all people who went trick-or-treating who received fruit in addition to candy is 0.24 and this number can be used for this problem. Which of the following is the correct answer? 204.13 123.14 304.13 123 305 205 304 124 204
An environmental health officer has been asked about levels of radon in homes in a particular county. As an initial step to forming a response to this inquiry, the officer plans to randomly select 20 homes in the county. The level of radon in each of the 20 homes will be measured, and the sample mean, x̅, and the sample standard deviation, s, will be calculated. Using these values, a 90% confidence interval will be constructed for the mean radon level for all homes in the county. Which of the following is the correct value of "t" for forming a confidence interval? a) 1.645 b) 1.328 c) 1.325 d) 1.725 e) 1.729
