How many pairs of shoes, on average, do female teens have? To find out, an AP®® Statistics class selected an SRS of 20 female students form their school. Then they recorded the number of pairs of shoes that each student reported having. This class also asked an SRS of 20 boys at their school how many pairs of shoes they have. A 95% confidence interval for ??−??=μG−μB= the true difference in the mean number of pairs of shoes for girls and boys is 10.9 to 26.5. Interpret the confidence interval. We are 95% confident that the interval from 10.9 to 26.5 captures the true difference (Girls – Boys) in the mean number of pairs of shoes owned by all girls and boys at this school. We are 95% confident that the interval from 10.9 to 26.5 captures the true mean difference (??????−????)(μGirls−Boys) in the number of pairs of shoes owned by all girls and boys at this school. Girls at this school have between 10.9 and 26.5 more pairs of shoes than boys 95% of the time. We are 95% confident…
Is the mean length of adult invasive Lionfish in the Atlantic coast of South Carolina greater than 355.6mm? (This is just the research question I using please just answer question 2 and 3 please.) Lower limit: 429.737 Upper limit: 445.163 Question 2. Interpret the above confidence intervals: Question 3. If you have one sample group, determine whether the value in your research question (the value which is compared to the population mean) is within the confidence interval or not. Then describe what it implies. If you have two groups of data, determine whether the confidence intervals of the two groups overlap or not. Then describe what that implies.
Sales personnel for Skillings Distributors submit weekly reports listing the customer contacts made during the week. A sample of 55 weekly reports showed a sample mean of 18.5 customer contacts per week. The sample standard deviation was 5.2. Provide 90% and 95% confidence intervals for the population mean number of weekly customer contacts for the sales personnel. 90% Confidence interval, to 2 decimals: 95% Confidence interval, to 2 decimals:
Forty adults used the Atkins weight loss program. After 12 months, their mean weight loss was found to be 2.1 lb with a standard deviation of 4.8 lb. You need to construct confidence interval estimate of mean weight loss for all such subject using a 90% confidence level. What is the significance level of this problem? Answer in a decimal.
At the local fish hatchery we take a random sample of 21 trout from one of the holding pens. The trout in the sample have a mean length of 11.2 inches with a standard deviation of .73 inches. Construct and interpret a 95% confidence interval for the mean length of all trout in this holding pen. Type your interpretation sentence in the written response box.
On average, adults spend approximately 5 hours per night in NREM (non-rapid eye movement) sleep. A sleep study selects a random sample of adults and gives them each a weighted blanket. They would like to know if using the weighted blanket changes the mean number of hours per night of NREM sleep. We want to test = 5 versus ≠ 5 where = the true mean hours of NREM sleep per night for adults who use a weighted blanket. A 99% confidence interval for the true mean hours of NREM sleep per night for adults who use a weighted blanket is (5.1, 5.8) hours. Based on the confidence interval, what conclusion would you make for a test of these hypotheses? The 99% confidence interval include as a plausible value, so we would H0. We convincing evidence that the true mean hours of NREM sleep per night for adults who use a weighted blanket 5 hours.
We have developed a new drug used to reduce fever and want to test its efficacy. Ten ER patients who are running a fever agree to take the new drug instead of the traditional treatment. Their temperatures are taken before the drug is administered and 30 minutes after taking the drug. The results are recorded in the Excel file below. Use the data to construct and interpret a 99% confidence interval for the mean change in temperatures of patients after taking this drug using Excel. Be sure to include any explanation necessary along with a sentence that explains what the interval means.

Suppose you work for the Department of Environment and National Resources (DENR). You want to estimate, with 95% confidence, the mean length of all tilapia in a fish hatchery pond. You take a random sample of 10 tilapia and determine the average length is 10.5 inches and the sample standard deviation is 2.9 inches. Construct a confidence interval for this sample and interpret the result.
Afra is working in a bank. She has randomly contacted 36 customers and has examined their average annual salary. She found that the average salary of this sample of customers is $68200 with a sample standard deviation of $2375. She needs to report the population average at 95% confidence interval. What is the range that she should report?
