Here are summary statistics for randomly selected weights of newborn girls: n= 240, x= 31.8 hg, s=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 29.1 hg < u< 34.7 hg with only 15 sample values, x= 31.9 hg, and s = 3.6 hg? What is the confidence interval for the population mean u? |hg < u< hg (Round to one decimal place as needed.)
When forming a confidence interval for matched-pair data the point estimate is the Select one: O A. standard deviation of the differences. OB. differences of the standard deviations. O C. mean of the differences. O D. difference of the means.
The class collected their data and found the mean of the dominant forearm maximum force was 34.2 +-3.4 kg . The mean non-dominant forearm maximum force was 28.5 +- 7.8 kg for their 95% confidence intervals. Would you conclude that the means are different?
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.

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…
During the nutrition research, the amount of consumed kilocalories per day was measured for 18 people - 10 women and 8 men. Results are as follows: Women: 1624, 1608, 2003, 1654, 1907, 1636, 1924, 1868, 1578, 2010; Men: 2360, 2547, 2524, 2056, 2172, 2464, 2253, 1954. Calculate a 95% confidence interval on the mean for women and men separately. Assume distribution to be normal. Round your answers to the nearest integer (e.g. 9876). Women: i i Men: i
You want to estimate the average difference in the number of complaints filed by women at work and the number of complaints filed by men at work. You took an SRS of 7 businesses and collected the following data for number of complaints in a year: men 1 3 2 4 6 3 5 women 8 7 6 3 5 12 15 Create a 90% confidence interval for the average difference in the number of complaints filed by women at work and the number of complaints filed by men at work (in a year). You must do this using table C. If this is a 2 sample interval, be sure to specify who is population 1 and who is population 2. If this is a matched pairs interval, be sure to state the order you subtracted your data. Once you create your interval, give a sentence explaining the meaning of the interval (what the numbers in the interval mean, NOT the meaning of 95%) in context of this problem. Round to any appropriate number of decimals.
Assume that the 95% confidence interval for mean=9 and standard devaition=20. For a particular data, the standardized value z = 2.73. We can say that: Select one: a. The data with standardized value 2.73 does not belong to the confidence interval and the value is less than the average. b. The data with standardized value 2.73 does not belong to the confidence interval and the value is greater than the average. c. Cannot interpret the z-value information provided. d. The data with standardized value 2.73 if it belongs to the confidence interval and the value is less than the average. e. The data with standardized value 2.73 if it belongs to the confidence interval and the value is greater than the average.
Which type of confidence interval should you use in this situation? A sample of 25 different payroll departments found that the employees worked an average of 310.3 days a year with a standard deviation of 23.8 days. The distribution is approximately normally distributed. Find the 90% confidence interval for the average days worked of all payroll departments. Question 2 options: 1) a confidence interval for the mean using a table value from the standard normal distribution. 2) a confidence interval for the mean using a table value from the t distribution. 3) a confidence interval for a proportion using a table value from the standard normal distribution. 4) a confidence interval for proportion using a table value from the t distribution. 5) none of the above.
Obesity is defined as a body mass index (BMI) of 30 kg/m2 or more. A 95% confidence interval for the percentage of U.S. adults aged 20 years and over who were obese was found to be 20.26% to 29.8%. What was the sample size?
Here are summary statistics for randomly selected weights of newborn girls: n=191, x=28.9 hg, s =7.8hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 27.1 hg<u<30.5 hg with only 13 sample values, x=28.8 hg, and s=3.5 hg? What is the confidence interval for the population mean u? Are the results between the two confidence intervals very different?
In the construction of an 88% Confidence Interval for a population mean u, a has the value of
