growth chamber fluctuates randomly, and you would like to estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: data: 77.2,59.9,77.6,76.4,74.7,79.9,81,62.3,60.3,85.8,91.9,64.7,73.6,79,73.1,81.1,69.5,95.5,63.6,62.3,76.4,78.5,54.8,79 In order to construct a 90% confidence interval, I need Sample size (amount), n Sample Mean (average), X population standard deviation ()
