Question 249765: You randomly select 16 coffee shops in Seattle and measure the temperature of the coffee sold at each. The sample mean temperature is 161.8 degrees farenheit with a sample standard deviation of 10.0 degrees (F) Find the 95% confidence interval estimate for the mean temperature for all coffee shopes in Seattle. Assume the temperatures are normally distributed.
95% = 1.96
std. deviation 10.1
161.8
n=16
The answer I got is 156.9 is less than 166.8
