Solution:- Given that values 96.7,98.6,97.3,96.8,97.6,99.8,99.9,96.9,99.1,98.9
x = 98.16 , S = 1.2456 , n = 10
df = n-1 = 10-1 = 9
t = 1.383
80% confidence interval of the mean high temperature : x +/-
t*s/sqrt(n)
: 98.16 +/- 1.383*1.2456/sqrt(10)
: 97.615 ,
98.705

You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately o = 52.6. You would like to be 90% confident that your estimate is within 2 of the true population mean. How large of a sample size is required?

You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 70.3 73.3 64.8 70 63.8 Find the 98% confidence interval. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place). 98% C.I. = Answer should be obtained without any preliminary rounding.
You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 73.5 64.1 45.3 53.9 58.7 Find the 99% confidence interval. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place). 99% C.I. = Answer should be obtained without any preliminary rounding.
