What is the confidence interval for the population mean μ​?   nothing hg<μ

Here are summary statistics for randomly selected weights of newborn​ girls: n=182​, x=27.4 ​hg, s=6.7 hg. Construct a confidence interval estimate of the mean. Use a 99​% confidence level. Are these results very different from the confidence interval 26.3 hg<μ<29.5 hg with only 16 sample​ values, x=27.9 ​hg, and s=2.2 ​hg? What is the confidence interval for the population mean μ​?     hg<μ<hg ​

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.)

Here are summary statistics for randomly selected weights of newborn girls: n = 224, x= 28.1 hg, s= 7.9 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 26.5 hg <µ<30.7 hg with only 14 sample values, x = 28.6 hg, and s= 3.7 hg? ... What is the confidence interval for the population mean μ? hg<μ

What are the confidence intervals for: Mean= 5.9 Sd= 3 N=200 α= .01

Are these results very different from the confidence interval 27.1 hg < µ< 29.7 hg with only 20 sample values, x= 28.4 hg, and s = 2.3 hg? What is the confidence interval for the population mean µ? hg < µ< hg (Round to one decimal place as needed.)

Here are summary statistics for randomly selected weights of newborn​ girls: n=217​, x=31.7hg, s=6.5hg. Construct a confidence interval estimate of the mean. Use a 98​% confidence level. Are these results very different from the confidence interval 29.6hg<μ<32.6hg with only 17 sample​ values, x=31.1​hg, and s=2.4​hg?   What is the confidence interval for the population mean μ​?   hg < μ < hg   ​(Round to one decimal place as​ needed.)

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.

Here are summary statistics for randomly selected weights of newborn girls: n = 171, x = 29.8 hg, s = 6.8 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 28.0 hg

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?
